Question

My fourth graders math homework and I need help with this

Answer 1

I totally agree with Jen because using the equation Jen gave will give us different equivalent fractions.

Let's define equivalent fractions to better understand how Jen's equation is right.

Equivalent fractions are fractions with different numerators and denominators but the values of the fractions are the same. For example, using Jen's equation;

Let's a =1 and b=2; and n = 2

`\begin{gathered} (1)/(2)=(2\ast1)/(2\ast2)=(2)/(4) \\ (1)/(2)=(2)/(4) \end{gathered}`

1/2 and 2/4 are equivalent because if we simplify 2/4, we'll have 1/2.

So Jen's equation is c
