Выполните действие : 4 3/8 - ( 3 5/7 - 1 5/7 ) + 1 5/8 = 12 7/12 - 4 5/12 - ( 20 3/4 - 19 3/4 ) = срочно надо плизззззззз!!!

Answer 1

1)4 3/8 - ( 3 5/7 - 1 5/7 ) + 1 5/8 =1)3 5/7-1 5/7=2; ///2)4 3/8-2=2 3/8; //3)2 3/8+1 5/8=4; /// 2)12 7/12 - 4 5/12 - ( 20 3/4 - 19 3/4 ) =1)20 3/4-19 3/4=1; //2)12 7/12-4 5/12=8 2/12; //3)8 2/12-1=7 2/12=7 1/6

Answer 2

4 3/8 - (3 5/7 - 1 5/7) + 1 5/8 = 4 3/8 - 2 + 1 5/8 = 2 3/8 + 1 5/8 = 3 8/8 = 4
12 7/12 - 4 5/12 - (20 3/4 - 19 3/4) = 12 7/12 - 4 5/12 - 1 = 8 2/12 - 1 = 7 2/12 = 7 1/6

Answer 3

Calculation:

To solve the given expression, let's break it down step by step:

1. 4 3/8 + (3 5/7 - 1 5/7) + 1 5/8

First, let's simplify the expression inside the parentheses:

3 5/7 - 1 5/7 = (3 + 5/7) - (1 + 5/7) = 3 + 5/7 - 1 - 5/7 = 2 + 0/7 = 2

Now, substitute the simplified expression back into the original expression:

4 3/8 + 2 + 1 5/8

Next, let's convert all the mixed numbers to improper fractions:

4 3/8 = (4 * 8 + 3) / 8 = 35/8

1 5/8 = (1 * 8 + 5) / 8 = 13/8

Now, substitute the improper fractions back into the expression:

35/8 + 2 + 13/8

Finally, let's add the fractions:

35/8 + 2 + 13/8 = (35 + 2 * 8 + 13) / 8 = 60/8 = 7 4/8 = 7 1/2

Therefore, the value of the expression is 7 1/2.

Answer:

The value of the expression 4 3/8 + (3 5/7 - 1 5/7) + 1 5/8 is 7 1/2.
