Question

(1,8+4,3)-(4/7-6/35)-5,7​

Answer 1

Ответ:

0,8

Пошаговое объяснение:

1,8 + 4,3 = 6,1

4/7 - 6/35 = 20/35 - 6/35 = 14/35 = 2/5 = 0,4

6,1 + 0,4 - 5,7 = 6,5 - 5,7 = 0,8

Answer 2

Let's solve the expression step by step:

(1,8 + 4,3) - (4/7 - 6/35) - 5,7

Step 1: Add the decimals within the parentheses: 1.8 + 4.3 = 6.1

Step 2: Subtract the fractions within the parentheses: 4/7 - 6/35 = (20/35) - (6/35) = 14/35 = 2/5

Step 3: Subtract the result of step 2 from the result of step 1: 6.1 - 2/5

To subtract a fraction from a decimal, you need to convert the fraction to a decimal. In this case, 2/5 as a decimal is 0.4.

6.1 - 0.4 = 5.7

Step 4: Subtract 5.7 from the result of step 3: 5.7 - 5.7 = 0

So, the final result of the expression is 0.
