Question

Сократите дроби:  6 * 15/5 * 12, 18 * 21/14*36, 81 * 12/24*45, 11 * 9/15 * 22, 45 * 17/17 * 35, 56 * 16/48 * 49

Answer 1

1) 6 и 12 ; 5 и 15  в ответе 3/2=1,5
остальные аналогично
2)3/4=0.75
3) 9/10=0.9
4)3/10=0.3
5)9/7
6) 8/21

Answer 2

Давайте сократим данные дроби:

1. $6 \times \frac{{15}}{{5}} \times 12 = 6 \times 3 \times 12 = 216$

2. $18 \times \frac{{21}}{{14}} \times 36 = 18 \times \frac{{3}}{{2}} \times 36 = 324 \times 3 = 972$

3. $81 \times \frac{{12}}{{24}} \times 45 = 81 \times \frac{{1}}{{2}} \times 45 = 40.5 \times 45 = 1822.5$

4. $11 \times \frac{{9}}{{15}} \times 22 = 11 \times \frac{{3}}{{5}} \times 22 = 11 \times 6.6 = 72.6$

5. $45 \times \frac{{17}}{{17}} \times 35 = 45 \times 1 \times 35 = 1575$

6. $56 \times \frac{{16}}{{48}} \times 49 = 56 \times \frac{{1}}{{3}} \times 49 = 28 \times 49 = 1372$

Таким образом, сокращенные дроби равны:

1. $216$
2. $972$
3. $1822.5$
4. $72.6$
5. $1575$
6. $1372$
