Answer 2

Calculation of the Expression

To find the value of the expression (-3/4 + 2/5) + (3.7 - 7.95) - (-3.6), we can follow the order of operations (PEMDAS/BODMAS) and perform the calculations step by step.

1. Simplify the fractions: - (-3/4 + 2/5) = (-15/20 + 8/20) = -7/20

2. Perform the addition and subtraction operations: - (-7/20) + (3.7 - 7.95) - (-3.6) = -7/20 + (-4.25) - (-3.6) - To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 20. - (-7/20) + (-4.25) - (-3.6) = (-7/20) + (-85/20) - (-72/20) - Combine the fractions with the same denominator: = (-7 - 85 + 72) / 20 = -20 / 20 = -1

Therefore, the value of the expression (-3/4 + 2/5) + (3.7 - 7.95) - (-3.6) is -1.
