Question

(17-8,5:3,4)•0,6; (5,4:3,6-1,3)•8,5; (1,8•3,4+0,88):0,35:

Answer 1

(17-8,5:3,4)*0,6=8,7

 1)8,5:3,4=2,5

  2)17-2,5=14,5

  3) 14,5*0,6=8,7

(5,4:3,6-1,3)*8,5=1,7

1)5,4:3,6=1,5

2)1,5-1,3=0,2

 3)0,2*8,5=1,7

(1,8*3,4+0,88):0,35=20

1)1,8*3,4=6,12

2)6,12+0,88=7

3)7:0,35=20

Answer 2

Let's break down each expression step by step:

1. (17-8,5:3,4) • 0,6:

First, we need to calculate the expression inside the parentheses: 17 - 8.5 = 8.5 Next, we divide 8.5 by 3.4: 8.5 / 3.4 = 2.5

Now, we can proceed with the entire expression: 2.5 • 0.6 = 1.5

So, (17-8.5:3.4) • 0.6 equals 1.5.

2. (5.4:3.6 - 1.3) • 8.5:

First, we need to calculate the expression inside the parentheses: 5.4 / 3.6 = 1.5 Next, we subtract 1.3 from 1.5: 1.5 - 1.3 = 0.2

Now, we can proceed with the entire expression: 0.2 • 8.5 = 1.7

So, (5.4:3.6 - 1.3) • 8.5 equals 1.7.

3. (1.8 • 3.4 + 0.88) : 0.35:

First, we calculate the multiplication: 1.8 • 3.4 = 6.12

Next, we add 0.88 to the result: 6.12 + 0.88 = 7

Finally, we divide 7 by 0.35: 7 / 0.35 = 20

So, (1.8 • 3.4 + 0.88) : 0.35 equals 20.

To summarize:

• (17-8.5:3.4) • 0.6 = 1.5
• (5.4:3.6 - 1.3) • 8.5 = 1.7
• (1.8 • 3.4 + 0.88) : 0.35 = 20
