Question

1/3 . 1/5 =

1/3 . 3/5 =

2/3 . 1/3 =

2/9 . 2 =

4/3 . 3 =
​

Answer 1

Resposta:

$\frac{1}{3} \times \frac{1}{5} = \frac{1}{15}$

$\frac{1}{3} \times \frac{3}{5} = \frac{3}{15} = \frac{1}{5}$

$\frac{2}{3} \times \frac{1}{3} = \frac{2}{9}$

$\frac{2}{9} \times \frac{2}{1} = \frac{4}{9}$

$\frac{4}{3} \times \frac{3}{1} = \frac{12}{3} = 4$
