How is multiplying rational numbers like multiplying fractions and multiplying decimals?

Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.


How is doing operations with rational expressions similar or different from doing equations with fractions and how can they be used in real life?

How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions?If you know how to do arithmetic with rational numbers you will understand the arithmetic with rational functions! Doing operations (adding, subtracting, multiplying, and dividing) is very similar. When you areadding or subtracting they both require a common denominator. When multiplying or dividing it works the same for instance reducing by factoring. Operations on rational expressions is similar to doing operations on fractions. You have to come up with a common denominator in order to add or subtract. To multiply the numerators and denominators separated. In division you flip the second fraction and multiply. The difference is that rational expressions can have variable letters and powers in them.


How is multiplying complex numbers similar to multiplying polynomials?

no


How is dividing fractions similar to multiplying fractions?

It is similar because when you divide fractions you are technically multiplying the second number's reciprocal. (Turning the fraction the other way around)

How is dividing decimals similar to dividing whole numbers?

In that you carry out exactly the same steps - AND you must determine the correct position of the decimal point.


How is solving a problem that includes rational numbers similar to solving a problem that includes irrational numbers?

Operations with rational numbers are carried out in exactly the same way as those for irrational numbers. There is, therefore, no difference in the methods for solving the two types of problems.

What is one step when multiplying fractions?

Multiplication of fractions is similar to multiplication of whole numbers. Often, multiplication of fractions can be made easier by first performing cancellation. Cancellation involves dividing both a numerator and a denominator by the same number. This is the same as dividing a fraction by one, and so it does not alter the answer. When cancelling, cross out the old terms and write in the new terms.


How is dividing fractions similar to multipying fractions?

Dividing anything by a fraction is equivalent to multiplying the same number by the reciprocal of the fraction. Thus, x / (p/q) = x * (q/p) where x is any number, and p and q are non-zero integers.

the answer is 12 you can find the answer by making factor trees and multiplying the similar prime numbers.


How dividing by decimal is similar from dividing whole number?

Consider 23/1.344 This can be written as 23000/1344 (we multiplied both numerator and denominator by 1000 and doing so does not change the original value). Lo and behold we have converted dividing by decimal to dividing whole numbers. Consider 23.089/4.6788 This can be written as 230890/46788 (we multiplied both numerator and denominator by 10000 and doing so does not change the original value). Lo and behold we have converted dividing by decimal to dividing whole numbers.


How is multiplying and dividing decimals similar to multiplying and dividing whole number?

Multiplying decimals: Example: 2.5 x 1.3 = 3.25 Start by removing the decimal points, thus: 25 x 13 = (the answer is 325) Both 2.5 and 1.3 have 1 decimal places, so 1 + 1 = 2 (decimal places) Counting 2 places, right to left, places the decimal point here: 3.25 Search Google for division of decimals - there are plenty of how to examples and help on the internet!


How dividing by decimal is different from dividing by whole number and how it is similar?

Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.


How is dividing 360 by 100 similar to dividing 3600 by 1000?

Because they are equivalent ratios


How do you multiply and divide integers?

Multiplying and dividing integers is real easy. All you have to do is do regular dividing and multiplying keeping in mind these simple rules: RULES: 1: When multiplying or dividing integers, when the numbers are a positive, positive they equal a positive. When the numbers are negative, negative they equal a positive. In other words, same signs equal positive. 2: This rule is very similar to the rule above. The only change is that when the signs are different, they equal a negative. ( negative, positive= negative, positive, negative= negative.) Please correct me if I'm wrong. Multiply integers- my notes from class positive x positive= positive positive x negative= negative negative x negative= positive Divide integers- again my notes from class positive divided by a positive= positive negative divided by a negative= positive negative divided by a positive= negative Dividing integers are simple if the number has a different sign than the other it is always negative but if they have the same sign its always positive ex. -20/5=-4 ex. -20/-4=-5


What is the difference between dividing and multiplying fractions?

They are similar. When dividing fractions, you multiply by the reciprocal. 2/5 divided by 3/4 is the same as 2/5 x 4/3


What does greatest common factor and least common multiple have in common?

They really aren't all that similar... Greastest common factor finds the greatest number that you can divide both numbers by... for example, the GCF of 15 and 20 is 5, because 15 / 3 = 5 and 20 / 4 = 5, there is no higher number for division purposes that the two share. 10 is higher than 5 in the case of 20, but you cannot divide 15 by 10 without getting a remainder of 5. Least common multiple finds the smallest common number that you can get when multiplying a number... for example, the LCM of 15 and 45 is 15 itself; 15 x 1 = 15, and 15 x 3 = 45. There is no smaller number that you can find that is common between the two. Another example, since the previous one had an LCM of an actual number being asked would be 18 and 24... in this case it would be 72 because there is no smaller number that the two share when multiplied by another value. They are somewhat similar in how you find the end value, however. By dividing the two given numbers in the case of LCM, you will eventually break them up into prime numbers. Eliminating all similar numbers and then multiplying what is left will give you the LCM. In the case of GCF, by doing the same thing minus multiplying the prime numbers, you will end up finding the greatest number that the two are divisible by.
