3/8 * 8/9 + 5/9 / (5/6) - 5/8 * 4/15 =

Accepted Answer

Решим выражения:

1) (3/4)/(1/2) - (3/4)/(3/4) = 3 * 2/4 - 1 = 6/4 - 1 = 1 1/2 - 1 = 1/2;

2) (3/20)/(7/10 - 1/5 * 1/2) = (3/20) : (7/10 - 1/10) = 3/20 : 6/10 = 3 * 10/(20 * 6) = 30/120 = 1/4;

3) (3/8)/(1/4) - (6/7)/(9/14) = 3 * 4/8 - 6 * 14/(7 * 9) = 12/8 - 12/9 = 3/2 - 4/3 = (9 - 8)/6 = 1/6;

4) 3/8 * 8/9 + (5/9)/(5/6 - 5/8 * 4/15) = 24/72 + (5/9)/(5/6 - 20/120) = 1/3 + (5/9)/(5/6 - 1/6) = 1/3 + 5/9 : 4/6 = 1/3 + 30/36 = 1/3 + 5/6 = (2 + 5)/6 = 7/6 = 1 1/6.

(3/4 / (1/2) - 3/4) / (3/4) = 3/20 / (7/10 - 1/5 * 1/2) = 3/8 / (1/4) - 6/7 / (9/14) = 3/8 * 8/9 + 5/9 / (5/6) - 5/8 * 4/15 =
