Question

Find the missing number to make these fractions equal.
4/5=12/ what

Answer 1

15

Explanation:

let
`{x}` be the unknown denominator.

therefore,

`(4)/(5)=(12)/(x)`

cross multiply

4
`{x\\}` = 12×5

`{x} = (12)/(4)` ×5

`{x} = 3` × 5

`{x} = 15`

therefore the missing number is 15

Answer 2

12/15

Explanation:

To find the answer to this question, we first need to align the numerators and find what multiplies by 4 to get 12.

This is achieved by dividing 12 by 4.

12 / 4 = 3

Now, we need to multiply 3 by the denominator (5) to get the missing denominator of the second fraction.

5 * 3 = 15 --> (Denominator)

Inputting the denominator into the second fraction, we have the fraction:

12/15
