Question

-36:(3 1/4 +2/3 •(-1,5) )-2 18/25​

Answer 1

Ответ:

Пошаговое объяснение:

2/3*(-1,5)=2/3*(-3/2)=-1

3 1/4+(-1)=2 1/4

-36:2 1/4=-36*4/9=-16

-16-2 18/25=-18 18/25

Answer 2

шаг 1) 2/3 × (–1,5)=2/3 × (–3/2)= –1

шаг 2) 3 1/4 + (–1)=2 1/4

шаг 3) –36 ÷ 2 1/4=-36 × 4/9= –16

шаг 4) –16 – 2 18/25= –18 18/25

Answer 3

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

Step 1: Simplify the expression inside the parentheses. -1.5 is the same as -3/2 in fraction form. Now, let's evaluate the expression inside the parentheses: 3 1/4 + 2/3 * (-3/2)

Step 2: Convert the mixed number to an improper fraction for easier calculation. 3 1/4 can be written as (4 * 3 + 1) / 4 = 13/4.

Step 3: Perform the multiplication: 2/3 * (-3/2) = (2 * -3) / (3 * 2) = -6 / 6 = -1.

Step 4: Add the results from steps 2 and 3: 13/4 + (-1) = 13/4 - 1 = 13/4 - 4/4 = 9/4.

Step 5: Now subtract the entire expression: -36 * (9/4) - 2 18/25.

Step 6: Convert 2 18/25 to an improper fraction: 2 18/25 = (25 * 2 + 18) / 25 = 68/25.

Step 7: Perform the subtraction: -36 * (9/4) - 68/25.

Step 8: Find the common denominator, which is 100 (4 * 25).

Step 9: Convert both fractions to have a denominator of 100: (100 * -36 * 9) / (4 * 25 * 4) - (68 * 4) / (25 * 4).

Step 10: Calculate the numerator of each fraction: -32 * 9 - 68 * 4.

Step 11: Perform the subtraction: -288 - 272 = -560.

The final result is -560.
