Приведите дроби 1/2 2/5 7/5 4/5 к знаменателю 10 1/4 3/20 8/25 7/25 1/50 к знаменателю 100 6/125 25/250 7/200 9/500

Приведем дроби к знаменателю 10:

1) 1/2 = (1 * 5) / 10 = 5/10;

2) 2/5 = (2 * 2) / 10 = 4/10;

3) 7/5 = (7 * 2) / 10 = 14/10;

4) 4/5 = (4 * 2) / 10 = 8/10.

Приведем дроби к знаменателю 100:

1) 1/4 = (1 * 25) / 100 = 25/100;

2) 3/20 = (3 * 5) / 100 = 15/100;

3) 8/25 = (8 * 4) / 100 = 32/100;

4) 7/25 = (7 * 4) / 100 = 28/100;

5) 1/50 = (1 * 2) / 100 = 2/100.

Приведем дроби к знаменателю 1000:

1) 6/125 = (6 * 8) / 1000 = 48/1000;

2) 25/250 = (25 * 4) / 1000 = 100/1000;

3) 7/200 = (7 * 5) / 1000 = 35/1000;

4) 9/500 = (9 * 2) / 1000 = 18/1000.
