Question

Найти значение выражения: 1/6 * (- 2.4) – (7/8 – 4)

Answer 1

1)1,6*(-2,4)=-3,84
2)7/8-4=7/8-32/8=-25/8
3)-3,84-(-25/8)=-3,84-(-3,125)=-3,84+3,125=-0,715

Answer 2

To find the value of the expression, simply 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 solve the expression step by step:

1. 1/6 * (-2.4) = -0.4 (multiplication)
2. (7/8 - 4) = -3.125 (subtraction)

Now, substitute the values back into the original expression:

-0.4 - (-3.125) = -0.4 + 3.125 = 2.725

So, the value of the expression is 2.725.
