Question

Помогите пожалуйста срочно надо. Вычислите 2 1/4*8/15 и 2,4*2 2/9

Answer 1

$2\frac{1}{4} \times \frac{8}{15} = \frac{9}{4} \times \frac{8}{15} = \frac{3}{1} \times \frac{2}{5} = \frac{6}{5} = \frac{12}{10} = 1.2$

$2.4 \times 2 \frac{2}{9} = \frac{24}{10} \times \frac{20}{9} = \frac{8}{1} \times \frac{2}{3} = \frac{16}{3} = 5 \frac{1}{3} = 5.(3)$
