Question

пожалуйста очень срочно

Answer 1

1) 1/3х + 1/4х + 1/8х = 34/45
17/24х = 34/45
х = 34/45 ÷ 17/24
х =
$1 \frac{1}{15}$
Ответ: х = 1 1/15


2) 3 3/4х - 1 2/3 = 2 11/12
3 3/4х = 2 11/12 + 1 2/3
3 3/4х = 4 7/12
х = 4 7/12 ÷ 3 3/4
х =
$1\frac{2}{9}$
Ответ: 1 2/9


3) 4 2/15 - 3 1/9х = 1 4/5
3 1/9х = 4 2/15 - 1 4/5
3 1/9х = 2 1/3
х = 2 1/3 ÷ 3 1/9
х =
$\frac{3}{4}$
Ответ: 3/4

4) 5/16х + 2 3/4 = 6 1/8
5/16х = 6 1/8 - 2 3/4
5/16х = 3 3/8
х = 3 3/8 ÷ 5/16
х =
$10 \frac{4}{5}$
Ответ: 10 4/5
