Question

(5,5-З 3/4):5 (2-0,8)*3/4​

Answer 1

(5,5-З 3/4):5 = 0.95

(2-0,8)*3/4 = 0.9

Answer 2

1)(5,5-З 3/4):5=7/20

1. 5,5- 3 3/4 = 55/10 -15/4= 220-150/40=70/40=7/4

2. 7/4:5=7/4*1/5= 7/20

2) (2-0,8)*3/4​= 9/10

1)2- 0,8= 2,0-0,8=1,2

2)1,2*3/4= 12/10 * 3/4= 9/10

Answer 3

Let's break down the expression step by step:

1. Start with the expression inside the parentheses: 5 - 3/4 = 5 - 0.75 = 4.25

2. Next, simplify the expression within the other set of parentheses: 2 - 0.8 = 2 - 0.8 = 1.2

3. Now, you have the following expression: (4.25) / 5 * (1.2)

4. First, divide 4.25 by 5: 4.25 / 5 = 0.85

5. Now, multiply the result by 1.2: 0.85 * 1.2 = 1.02

So, the final result of the expression is 1.02.
