Question

1)4/5*7/12 2) 2 1/8*1 3/25 3) 5/11*33
​

Answer 1

Ответ:

$\frac{4}{5}\times\frac{7}{12} = \frac{4 \times 7}{5 \times 12} = \frac{28}{60} = \frac{7}{15}$

$2 \frac{1}{8} \times 1 \frac{3}{25} = \frac{17}{8} \times \frac{28}{25} = \frac{17 \times 28}{8 \times 25} = \frac{17 \times 7}{2 \times 25} = 2 \frac{19}{50}$

$\frac{5}{11} \times 33 = \frac{5 \times 33}{11} = \frac{5 \times 3}{1} = 15$
