How do you find a missing numerator?

Answer 1

Common numerator of 1/2 and 3/10

(multiply 1/2 by 3)


3/6 and 3/10 now have common numerators

Answer 2

Well, honey, if you're missing a numerator, you better start by looking under the couch cushions or in the junk drawer - just kidding! To find a missing numerator in a fraction, you'll need to use some good old-fashioned algebra. Set up an equation with the fraction, solve for the missing numerator by cross multiplying, and voila, you've found that sneaky little number.

Answer 3

Oh, dude, finding a missing numerator is like finding your keys in the morning - you just gotta look for it. So, if you have a fraction with a missing numerator, you can solve for it by setting up an equation where the fraction equals a known value and then solve for the missing numerator. It's not rocket science, but hey, it's math!

Answer 4

When doing changing fractions to equivalent fractions, if you multiply or divide the denominator by a number, you have to do the same to the numerator. Here is an example:

2/3 + 4/5 =

To find the LCM of 3 and 5, list the multiples of each until you find one that they have in common:

3, 6, 9, 12, 15, 18...

5, 10, 15, 20...

15 is the LCM.

To change the 3 in 2/3 to 15, multiply it by 5. Since you multiplied 3 by 5, you have to multiply the 2 by 5. The equialent fraction is 10/15.

To change the 5 in 4/5 to 15, multiply it by 3. 3 x 5 = 15. Now, you have to do the same to the numerator 4. 3 x 4 = 12. The fraction is 12/15.

Now, you can add the fractions together:

10/15 + 12/15 = 22/15, but it is an improper fraction, so you need to change it to a mixed number. To find the whole number, divide the numberator by the denominator. 22 divided by 15 is 1 with a remainder of 7. Use the 7 as the numerator and the 12 (the number you divided by) as the denominator.

The answer is 1 7/12. It is in simplest form because 7 is a Prime number that will not divide evenly into 12.

Answer 5

If you have 2 fractions like this: 2/4 and ?/8 First, 8 Divided by 4 is 2, so multiply 2x2, equals 4. The answer is 4/8

Answer 6

12=6/8

Answer 7

12= 6/8

Answer 8
