We have two fractions, \dfrac{5}{12}

12

5



start fraction, 5, divided by, 12, end fraction and \dfrac{3}{4}

4

3



start fraction, 3, divided by, 4, end fraction, and we want to rewrite them so that they have a common denominator (and whole number numerators).

what numbers could we use for the denominator?

B. 12

C. 24

Step-by-step explanation:

We have been given two fractions and . We are asked rewrite them so that they have a common denominator (and whole number numerators).

We can see that denominator of first number is 12 and denominator of 2nd number is 4.

We need to find least common denominator of 12 and 4.

Multiples of 12: 12, 24, 36, 48, 60, ...

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36,...

We can see that least common denominator is 12 and multiples of 12 are 12, 24.

Therefore, we can use 12 and 24 for the denominator.
