Question

4/3+(-5 1/2+5/4*3 1/5):9/10помогите пожалуйста ​

Answer 1

Ответ:

Пошаговое объяснение:

1) 5/4 * 3. 1/5 = 5/4 * 16/5 = 1/1 * 4/1 = 4/1 = 4

2) -5. 1/2 + 4 = -1. 1/2

3) -1. 1/2 : 9/10 = -3/2 : 9/10 = -3/2 * 10/9 = -1/1 * 5/3 = -5/3

4) 4/3 + (-5/3) = 4/3 - 5/3 = - 1/3

Answer 2

Пошаговое объяснение:

4/3+(-5 1/2+5/4×3 1/5):9/10= - 1/3

1) 5/4×3 1/5=5/4×16/5=4

2) - 5 1/2+4 = - 1 1/2

3) - 1 1/2:9/10= - 3/2×10/9= - 5/3

4) 4/3+(-5/3)=4/3-5/3= - 1/3

Answer 3

To solve the expression 4/3 + (-5 + 1/2 + 5/4 * 3 + 1/5) ÷ 9/10, 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:

1. Simplify the expression inside the parentheses: - (-5 + 1/2 + 5/4 * 3 + 1/5) = -5 + 1/2 + 15/4 + 1/5

2. Simplify the multiplication and division within the expression: - 5/4 * 3 = 15/4

3. Combine the terms within the expression: - -5 + 1/2 + 15/4 + 1/5 = -20/4 + 2/4 + 15/4 + 1/5

4. Find a common denominator for the fractions: - The common denominator for 4, 2, and 5 is 20.

5. Rewrite the fractions with the common denominator: - -20/4 + 2/4 + 15/4 + 1/5 = -20/20 + 40/20 + 75/20 + 4/20

6. Combine the fractions: - -20/20 + 40/20 + 75/20 + 4/20 = 99/20

7. Divide the result by 9/10: - (99/20) ÷ (9/10) = (99/20) * (10/9)
