Запишите десятичные лроби в виде обыкновеных дробей. Выполните действия. (3 5/6 - 1 2/15) * 5/9 + ((1/20 + 0,24) * 8 1/3 - 1 1/6) * 2 = 4

(3_5/6 - 1_2/15) * 5/9 + ((1/20+0,24) * 8_1/3 - 1_1/6) * 2 = 4

1 3 7 2 4 5 6

1) 3_5/6 - 1_2/15 = 3_25/30 - 1_ 4/30 = 2_21/30 = 2_7/10 = 2,7

2) 1/20 + 0,24 = 0,05+0,24 = 0,29 = 29/100

3) 2_7/10 * 5/9 = 27/10 * 5/9 = (27*5) / (10*9) = 3/2 = 1_1/2

4) 29/100 * 8_1/3 = 29/100 * 25/3 = 29/12 = 2_5/12

5) 2_ 5/12 - 1_ 1 / 6 = 2_ 5/12 - 1_2/12 = 1_3/12 = 1_1/4

6) 1_1/4 * 2 = 5/4 * 2 = 10/4 = 5/2 = 2_1/2

7) 1_1/2 + 2_1/2 = 4
