1)2,5 (-32) · (-0,4) = 2,5 × (-32) × (-0,4) = -32 × 2,5 × 0,4 = -32 × 1 = -32
2)-2/7 × (-3) × 14 = (-2/7) × (-3) × 14 = 6 × 2 = 12
3)-5/13 × (27) × 13/15 = -5/13 × 27/1 × 13/15 = -175/13
4)-25 × 0,3 × 4 = -3 × 4 = -12
Пошаговое объяснение:
To solve these calculations, we'll use the order of operations or PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
2,5 (-32) · (-0,4):
We can simplify this expression as follows:
2,5 (-32) · (-0,4) = 2,5 × (-32) × (-0,4) = -32 × 2,5 × 0,4 = -32 × 1 = -32
Therefore, the result is -32.
-2/7 × (-3) × 14:
We can simplify this expression as follows:
-2/7 × (-3) × 14 = (-2/7) × (-3) × 14 = 6 × 2 = 12
Therefore, the result is 12.
-5/13 × (27) × 13/15:
We can simplify this expression as follows:
-5/13 × (27) × 13/15 = -5/13 × 27/1 × 13/15 = -175/13
Therefore, the result is -175/13.
-25 × 0,3 × 4:
We can simplify this expression as follows:
-25 × 0,3 × 4 = -3 × 4 = -12
Therefore, the result is -12.
