Question

1/5 x 4/3 =
0.4 x 2/3 =
0.7 x 7/9 =
2.5 x 7/9 =
1/4 x 2/3 =
0.3 x 2/9 =​

Answer 1

Explicación paso a paso:

$\frac{1}{5} \times \frac{4}{3} = \frac{4}{15}$

$0.4 \times \frac{2}{3} = \frac{4}{10} \times \frac{2}{3} = \frac{8}{30} = \frac{4}{15}$

$0.7 \times \frac{7}{9} = \frac{7}{10} \times \frac{7}{9} = \frac{49}{90}$

$2.5 \times \frac{7}{9} = \frac{1}{4} \times \frac{7}{9} = \frac{7}{36}$

$\frac{1}{4} \times \frac{2}{3} = \frac{2}{12} = \frac{1}{6}$

$0.3 \times \frac{2}{9} = \frac{3}{10} \times \frac{2}{9} = \frac{6}{90} = \frac{1}{15}$
