Question

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

Answer 1

Answer:

12/15

Step-by-step 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

Answer 2

Answer:

15

Step-by-step explanation:

let ${x}$ be the unknown denominator.

therefore,

$\frac{4}{5}=\frac{12}{x}$

cross multiply

4${x\\}$ = 12×5

${x} = \frac{12}{4}$ ×5

${x} = 3$ × 5

${x} = 15$

therefore the missing number is 15
