It does not matter what they are as long as both are the same. 1 = 2/2 = 17/17 = 958/958 and so on.

Which is the dividend in a fraction?

In a fraction there is a numerator and a denominator. The numerator is the top number the denominator the bottom. The numerator is the divedend, the denominator is the divisor Think: in a house method problem- the divedend is on the end, the divisor is knocking at the door.

What do you turn the second fraction into in a dividing problem?

When dividing by a fraction, the second fraction (the divisor) is changed into its reciprocal by swapping the numerator and denominator over (turning it upside down) and then it is multiplied by the first number (fraction).

What is 46 over 63 - 3 over 11?

To calculate this sort of subtraction problem the two fractions have to be converted so that they share the same denominator - the number below the line. This is done by calculating the lowest common denominator they share. As 11 is a prime and 63 is not a multiple of it, then the lowest common denominator will be 63 x 11 = 693. * To convert the 46/63 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 11. This gives 506/693. * To convert the 3/11 to a fraction with 693 as its denominator we need to multiply both the numerator and the denominator by 63. This gives 189/693. Now we can subtract 189 from 506. That gives 317. * 317/693 As 317 is a prime, and 693 is not a multiple of it, that fraction can not be simplified.

How do you convert gram per cubic centimeters to kg per cubic meter explain?

You can multiply anything by 1 without changing it, a fraction with a numerator that's equal to its denominator equals 1, and common factors between a fraction's numerator and denominator cancel out. Also, whenever you see the word per in a word problem, think division.You're converting a fraction with grams in the numerator and cubic centimeters in the denominator to one with kilograms in numerator and cubic meters in the denominator. Therefore, you want to multiply by a fraction with grams in the denominator (to cancel out the grams) and kilograms in the numerator, and you want the quantities to be equal so the fraction equals 1. You also want to multiply by a fraction with cubic centimeters in the numerator (to cancel out the cubic centimeters) and cubic meters in the numerator that equals 1....(1 g/cm2) * (kg/1000g) * (10000 cm2/m2) = 10 kg/m2Since the second and third fractions each equals 1,1 g/cm2 = 10 kg/m2

What does east common denominator means?

Least common denominators are the smallest denominator you can go without the numerator being a fraction or decimal. 12/20 can be defined as 6/10 or 3/5, depending on the problem.

How do you find the LCD when subtracting rational expressions?

Given two fractions, you find the Least Common Denominator by finding the Least Common Multiple of the two Denominators. Then for each fraction, the new numerator the product of the is old numerator, and whatever multiplier you use to get the new denominator. Example: 1/14 - 1/21: The LCM of 14 & 21 is 42, so for the first fraction: 3 x 14 = 42, so the new numerator is 3 x 1 = 3. For the 2nd fraction: 2 x 21 = 42, so the new numerator is 2 x 1 = 2. The new subtraction problem is: 3/42 - 2/42 = 1/42

What is 179 and 3 8th divided by 2?

If we convert 179 and 3/8 into a improper fraction, it becomes 1435/8. Also, 2 can be written as 2/1 in fraction form.To divide fractions, we must first switch the numerator and denominator of the second fraction. In this case, the second fraction is 2/1. By switching the numerator and denominator, it becomes 1/2.Then we can turn it into a multiplication problem. Like so:Your problem is now: 1435/8 * 1/2Simplify: 1435/1689.6875 OR 89 and 11/16

How do you you add a fractions when the denominator is not the same?

ok this is like 5th grade math but you have to multiply. Say it is 1/4+3/8. You have to multiply the lower denominator which in this case is 4 to get it to 8. Which you get 4x2=8 right. Well whatever you do to the denominator you have to do to the numerator. so the numerator is 1 in the fraction of 1/4 and you get 1x2=2. So then your problem is 2/8+3/8= 5/8. If your worried that the denominator will not go into it dont because you will never get a problem like that

How do you estimate a percentage when the denominator is a negative number?

Work the problem the same as usual, but then prefix the answer with the appropriate sign. First perform the division--numerator divided by the denominator--without regard to the sign. The sign of your answer depends on the combination of the signs of the numerator, the denominator, and the fraction itself. * If there are an even number of minus signs, the answer is positive. * If there are an odd number of minus signs, the answer is negative. * If there are an no minus signs, the answer is positive.

How do you answer fraction problems?

The best way to answer fraction problems is with a fraction that has the same denominator or a common denominator with those in the original problem. Typically you also need to reduce it so that the final answer does not contain an improper fraction.

How do you get a fraction of another fraction?

To get a fraction of another fraction you have to multiply the fractions. To multiply fractions, just use this simple algorithm: Step 1-Turn all whole numbers and mixed numbers into improper fractions. Step 2-Multiply the numerators of the 2 fractions. The answer to that problem will be the numerator of the answer. Step 3-Multiply the denominators of the 2 fractions. The answer to that problem will be the denominator of the answer. Step 4-Reduce.
