Question

42-(12 12/15+ 10 7/15)

Answer 1

−45,9333333333 ........

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 solve the expression step by step:

1. First, simplify the fraction inside the parentheses: 12 12/15 = 12 + 12/15 = 12 + 4/5 = 12 + 0.8 = 12.8

10 7/15 = 10 + 7/15 = 10 + 0.4666... ≈ 10.4667

2. Now, perform the addition inside the parentheses: 12.8 + 10.4667 ≈ 23.2667

3. Finally, subtract the result from 42: 42 - 23.2667 ≈ 18.7333

So, the result of the expression is approximately 18.7333.
