Приведите дроби к несократимому виду 25/150,48/56/,60/75,45/100,800/900,120/140.

Приведем дроби к несократимому виду:

1) 25/150 = (5 * 5)/(5 * 30) = 5 * 1/(1 * 30) = 5/30 = 5/(5 * 6) = 1/(1 * 6) = 1/6;

2) 48/56 = (8 * 9)/(8 * 7) = (1 * 9)/(1 * 7)  = 9/7;

3) 60/75 = (5 * 12)/(5 * 15) = 1 * 12/(1 * 15) = 12/15 = 3 * 4/(3 * 5) = 1 * 4/(1 * 5) = 4/5;

4) 45/100 = (5 * 9)/(5 * 20) = 1 * 9/(1 * 20) = 9/20;

5) 800/900 = 8 * 100/(9 * 100) = 8 * 1/(9 * 1) = 8/9;

6) 120/140 = 12 * 10/(14 * 10) = 12 * 1/(14 * 1) = 12/14 = 2 * 6/(2 * 7) = 1 * 6/(1 * 7) = 6/7.
