Question

Use a common denominator to find equivalent tractions for and Enter the correct fractions in the boxes. 3 5 8 9 5 6 3

Answer 1

5/20 and 12/20

1) Since we have 1/4 and 3/5 let's prime factorize those denominators:

2) So let's turn those fractions into equivalent ones (keeping the same ratio):

`\begin{gathered} (1)/(4)*(5)/(5)=(5)/(20) \\ (3)/(5)*(4)/(4)=(12)/(20) \end{gathered}`

3) Hence the equivalent fractions are 5/20 and 12/20 since they keep the same ratio (1/4 and 3/5).
