Alyssa said the 6/8 and 9/12 are not equivalent because there is no whole number you can multiply both parts of 6/8 by to get 9/12. Is she correct? Explain.

Question

Alyssa said the 6/8 and 9/12 are not equivalent because there is no whole number you can multiply both parts of 6/8 by to get 9/12. Is she correct? Explain.

Answer 1

1 - If you cross-multiply the fractions,

the result would be 72, therefore, they

indeed are equivalent.

 

2 - If you reduce both fractions, the

reduction is 3/4, which makes them

equivalent.
