Question

Multiply the fractions. Write your answers in simplest form. 1/2 x 2/5

Answer 1

First make it that both denominators are the same.
$(\frac{1}{2} \times 5) + ( \frac{2}{5} \times 2) = \frac{5}{10} + \frac{4}{10}$
Then add both numerators
$\frac{5}{10} + \frac{4}{10} = \frac{9}{10}$
Your final answer should be
$\frac{9}{10}$

Answer 2

$\frac{1}{5}$

$\frac{1}{2}$ × $\frac{2}{5}$

= $\frac{1(2)}{2(5)}$ = $\frac{2}{10}$ = $\frac{1}{5}$ in simplest form ( cancelling 2 and 10 by 2 )
