Which fraction is equivalent to<br> 2/5

My name is Ann [436]

Answer:

To make equivalent fractions, what we have to do is multiplicate or divide the numerator or denominator by the same number.

In our case:

$\frac{2}{5}=\frac{2*2}{5*2}=\frac{4}{10}$

$\frac{2}{5}=\frac{2*6}{5*6}=\frac{12}{30}$

$\frac{2}{5} = \frac{2*12}{5*12}=\frac{24}{60}$

That are only three examples, but there are infinite.

We could also obtain equivalent fractions dividing, for example, $\frac{3}{9}$ :

$\frac{3}{9}=\frac{\frac{3}{3}}{\frac{9}{3}}$ = $\frac{1}{3}$
