Question

помогите срочно!!!
$x \times 1 \frac{3 }{5 } = 3 \frac{1}{15}$
$y \div1 \frac{3}{4} = 7$
​

Answer 1

1) х × 1 3/5 = 3 1/15

x = 3 1/15 ÷ 1 3/5

х = 46/15 ÷ 8/5

х = 46/25 × 5/8

х = 23/5 × 1/4

х = 23/20

Ответ: х = 1 3/20

2) d ÷ 1 3/4 = 7

d = 7 × 1 3/4

d = 7 × 7/3

d = 21/4

Ответ: d = 5 1/4
