Question

(4,75-17/8)÷0,8= (1-0,532)÷13/20=

Answer 1

(4,75-17/8):0,8=4,75-17/8= 2,625:0,8= 3,28
(1-0,532):13/20=1-0,532= 0,468:13/20=0,72

Answer 2

To solve the given expressions, let's break them down step by step:

Expression 1: (4.75 - 17/8) ÷ 0.8

Step 1: Simplify the numerator within parentheses: 4.75 - 17/8 = 4.75 - 2.125 = 2.625

Step 2: Divide the numerator by 0.8: 2.625 ÷ 0.8 = 3.28125

Therefore, the value of the first expression is 3.28125.

Expression 2: (1 - 0.532) ÷ (13/20)

Step 1: Subtract the values within parentheses: 1 - 0.532 = 0.468

Step 2: Divide the result by (13/20): 0.468 ÷ (13/20) = 0.468 × (20/13) = 0.720

Therefore, the value of the second expression is 0.720.
