Answer 1

Ответ:

Пошаговое объяснение:

1) -27/20 *(-5/9) = 3/4 = 0,75

2) 5/24 * (-12/5) = -1/2 = -0,5

3) 0,75 - (-0,5) = 0,75 + 0,5 = 1,25

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. Start with the division in parentheses: (-5/9) = -0.55556... (rounded to 5 decimal places) (-12/5) = -2.4

2. Next, multiply the fractions outside the parentheses: (-27/20) * (-0.55556...) = 0.771605... (rounded to 6 decimal places) (-5/24) * (-2.4) = 0.208333...

3. Finally, subtract the results: 0.771605... - 0.208333... = 0.563272...

Rounded to a reasonable number of decimal places, the result is approximately: 0.5633
