Question

Найдите разность 3/8-1/8; 5/9-2/9; 2/15-2/15;; 17/19-16/19; 21/100-11/100;83/110-13/110.

Answer 1

2/8=1/4

3/9=1/3

0/15=0

1/19

10/100=1/10=0,1

70/110=7/11

Answer 2

1) 3/8 - 1/8 = 1/4;
2) 5/9 - 2/9 = 1/3;
3) 2/15 - 2/15 = 0;
4) 17/19 - 16/19 = 1/19;
5) 21/100 - 11/100 = 1/10 = 0.1;
6) 83/110 - 13/110 = 7/11.

Answer 3

Давайте найдем разность для каждой пары дробей:

1. 3/8 - 1/8 = (3 - 1) / 8 = 2 / 8 = 1 / 4

2. 5/9 - 2/9 = (5 - 2) / 9 = 3 / 9 = 1 / 3

3. 2/15 - 2/15 = (2 - 2) / 15 = 0 / 15 = 0

4. 17/19 - 16/19 = (17 - 16) / 19 = 1 / 19

5. 21/100 - 11/100 = (21 - 11) / 100 = 10 / 100 = 1 / 10

6. 83/110 - 13/110 = (83 - 13) / 110 = 70 / 110 = 7 / 11

Таким образом, разности дробей равны:

1/4; 1/3; 0; 1/19; 1/10; 7/11.
