How are reciprocals used when dividing fractions?
When dividing fractions, take the reciprocal of the second fraction, and multiply the first fraction by the reciprocal of the second fraction. Example: (a/b)/(c/d)=(a/b)*(d/c)
Is the reciprocal used to divide fractions?
In order to divide two fractions, multiply the first times the reciprocal of the second.
When multiplying two mixed numbers the reciprocal of the second mixed number must be used true or false?
False.
What is the reciprocal of 7.6?
The reciprocal of a number is simply 1 divided by that number. Therefore, the reciprocal of 7.6 is 1/7.6, which can also be expressed as approximately 0.1316 when rounded to four decimal places. The reciprocal is used in mathematics to solve equations involving fractions and proportions.
Why do you multiply and divide functions?
To multiply fractions you take the first fractions top, or the numerator, times the second fractions top. This is the top to the answer. Then you take the first fractions bottom, or denominator, times the second fractions bottom. This is the answers bottom. 2/3*7/5=14/5 To divide fractions, you take the second fraction and flip it over. Then you continue the same way as multiplying fractions, taking the first fraction times the flipped over second fraction. (2/3)/(7/5)=2/3*5/7=10/21
Why do you need to find the reciprocal of the divisor when dividing a fraction?
It is not just in fractions. In general, division can be defined as multiplication by the reciprocal. For example, dividing by 5 is the same as multiplying by 0.2. However, it is mainly in calculations with fractions that this is normally used as a practical way of doing the calculations.
How are reciprocals used when dividing fractions?
When dividing fractions, take the reciprocal of the second fraction, and multiply the first fraction by the reciprocal of the second fraction. Example: (a/b)/(c/d)=(a/b)*(d/c)
What is a calculater used for?
A calculator is used for adding, subtracting, dividing, multiplying, decimals, or fractions and is also used for a lot of other uses too.
Is the reciprocal used to divide fractions?
In order to divide two fractions, multiply the first times the reciprocal of the second.

Why are subtraction addition multiplication division called reciprocal or inverse operations?
The inverse operation of addition would be subtraction. The inverse operation of subtraction would be addition. The inverse operation of multiplication is division and the inverse operation of division is multiplication. It is called the inverse operation because you are reversing the equation. If you add, subtract, multiply, or divide the same number on each side of the equation, then the equation would still be true. As long as you are doing the same thing on BOTH side of the equation. The reciprocal is used for dividing fractions. All you have to do for finding the reciprocal of a fraction is flip the fraction. Ex: The reciprocal of 1/4 is 4. The reciprocal of 5/8 is 8/5. You can check by multiplying the two fractions. It will equal to one if you did it right. I hope this helped a little bit.
What is the reciprocal of -73?
With no other defining information, the reciprocal of 73 would be 1/73 . Reciprocals are usually used with fractions, but you can say, 'What is the reciprocal of 73/1' and get the same results.
When multiplying two mixed numbers the reciprocal of the second mixed number must be used true or false?
False.
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.
What is the reciprocal frequency?
The reciprocal frequency is the inverse of the frequency, calculated by dividing 1 by the frequency value. It is commonly used in physics and engineering to describe the time period corresponding to a specific frequency.
