Answer 1

Ответ:

Пошаговое объяснение:

6 1/4*8=25/4*8=50

3 2/3*5 1/2=11/3*11/2=121/6=20 1/6

2 2/5*4 7/12=12/5*55/12=11

50-20 1/6=29 5/6

29 5/6+11=40 5/6

Answer 2

To solve the expression, let's break it down step by step using the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Step 1: Perform multiplication and division from left to right. 6 1/4 × 8 = 6.25 × 8 = 50 3 2/3 × 5 1/2 = (11/3) × (11/2) = 121/6 ≈ 20.17 2 2/5 × 4 7/12 = (12/5) × (55/12) = 22/1 ≈ 22

Now we have: 50 - 20.17 + 22

Step 2: Perform addition and subtraction from left to right. 50 - 20.17 = 29.83 29.83 + 22 = 51.83

Therefore, the result of the expression 6 1/4 × 8 - 3 2/3 × 5 1/2 + 2 2/5 × 4 7/12 is approximately 51.83.
