Question

Решить 2 выражения 1) (3,4 поделить 1,7+0,57поделить 1,9) умножить 4,9 +0,0825 поделить 2,75-0,8 2) (4,44поделить 3,7-0,56 поделить 2,8 )поделить 0,25 -0,8.Зарание спасибо огромное!

Answer 1

1) (3,4÷1,7+0,57÷1,9)×4,9+0,0825÷2,75-0,8=(2+0,3)×4,9+0,03-0,8=2,3×4,9+0,03-0,8=11,27+0,03-0,8=10,5
2)(4,44÷3,7-0,56÷2,8)÷0,25-0,8=(1,2-0,2)÷0,25-0,8=1÷0,25-0,8=4-0,8=3,2

Answer 2

Solving the Expressions

Let's solve the given expressions step by step.

1. Expression 1: (3.4 / 1.7 + 0.57 / 1.9) * 4.9 + 0.0825 / 2.75 - 0.8 * 2 2. Expression 2: (4.44 / 3.7 - 0.56 / 2.8) / 0.25 - 0.8

Solution

1. Expression 1: - First, let's solve the division parts: - 3.4 / 1.7 = 2 - 0.57 / 1.9 = 0.3 - Then, we add the results: 2 + 0.3 = 2.3 - Next, we proceed with the multiplication and division: - 2.3 * 4.9 = 11.27 - 0.0825 / 2.75 = 0.03 - 0.03 - 0.8 * 2 = -1.57 - Therefore, the result of Expression 1 is -1.57.

2. Expression 2: - First, let's solve the division and subtraction parts: - 4.44 / 3.7 = 1.2 - 0.56 / 2.8 = 0.2 - 1.2 - 0.2 = 1 - Then, we proceed with the final division and subtraction: - 1 / 0.25 = 4 - 4 - 0.8 = 3.2 - Therefore, the result of Expression 2 is 3.2.

So, the solutions to the given expressions are: 1. Expression 1: -1.57 2. Expression 2: 3.2
