Question

(3 1/14-2 5/21)•(2 7/10-2 1/10) С объяснением!!!!!!!пожалуйста!! Пожалуйста !!!!

Answer 1

1) 3 1/14- 2 5/21 = 43/14-47/21=-6/14
2) 2 7/10 - 2 1/10 = 27/10 - 21/10 = 6/10
3) -6/14 * 6/10 = -9/35

Answer 2

To solve the given expression (3 + 1/14 - 2 + 5/21) * (2 + 7/10 - 2 + 1/10), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

Step 1: Simplify the expression inside the parentheses. (3 + 1/14 - 2 + 5/21) * (2 + 7/10 - 2 + 1/10)

Inside the first set of parentheses: 3 + 1/14 - 2 + 5/21 = 3 - 2 + 1/14 + 5/21

Step 2: Simplify the expression inside the second set of parentheses. 2 + 7/10 - 2 + 1/10 = 2 - 2 + 7/10 + 1/10

Now, let's simplify each part separately:

Step 3: Simplify the addition and subtraction within each set of parentheses.

For the first set of parentheses: 3 - 2 + 1/14 + 5/21 = 1 + 1/14 + 5/21

For the second set of parentheses: 2 - 2 + 7/10 + 1/10 = 0 + 7/10 + 1/10

Step 4: Simplify the addition and subtraction within each set of parentheses.

For the first set of parentheses: 1 + 1/14 + 5/21 = 1 + 1/14 + 5/21 = 1 + 1/14 + 5/21
