Question

7 класс вычислить (3/5+1/15)*(6,5-17,5)

Answer 1

(3/5+1/15)*(6,5-17,5)=3\5+1\15=9+1\15=10\15=2\3.
6,5-17,5=-11.
2\3*(-11)=2*11\3=22\3=7 1\3.

Answer 2

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

1. Perform the addition inside the parentheses: (3/5 + 1/15) = (9/15 + 1/15) = 10/15 = 2/3

2. Perform the multiplication: (2/3) * (6.5 - 17.5) = (2/3) * (-11) = -22/3 ≈ -7.33

So, the result of the expression is approximately -7.33.
