Question

((7/9-47/72)÷1,25+( 6/7-17/28)÷(0,358-0,108)​

Answer 1

Ответ:

Пошаговое объяснение:

1) 7/9 - 47/72 = 56/72 - 47/72 = 9/72 = 1/8

2) 1/8 : 1,25 = 0,125 : 1,25 = 0,1

3) 6/7 - 17/28 = 24/28 - 17/28 = 7/28 = 1/4 = 0,25

4) 0,1 + 0,25 = 0,35

5) 0,358 - 0,108 = 0,25

6) 0,35 : 0,25 = 1,4

Answer 2

To simplify the expression ((7/9 - 47/72) ÷ 1.25 + (6/7 - 17/28) ÷ (0.358 - 0.108)), you can follow these steps:

Step 1: Simplify each fraction separately:

• (7/9 - 47/72) = (56/72 - 47/72) = (9/72)

• (6/7 - 17/28) = (24/28 - 17/28) = (7/28)

Step 2: Perform the division within parentheses:

• (9/72) ÷ 1.25 = (9/72) ÷ (5/4) = (9/72) * (4/5) = (36/360)

• (7/28) ÷ (0.358 - 0.108) = (7/28) ÷ (0.25) = (7/28) * (4/1) = (28/28) = 1

Step 3: Add the results of the two divisions:

(36/360) + 1 = 0.1 + 1 = 1.1

So, the simplified value of the expression is 1.1.
