To simplify the expression -8 ÷ 35 + 15 using mental math, we can start by dividing -8 by 35. This gives us approximately -0.2286.
Then, we add 15 to this result: -0.2286 + 15 = 14.7714.
Rounding this to the nearest whole number, we get 15.
Therefore, the simplified expression is 15.
So, the correct answer is 15.
To simplify the expression using mental math, follow these steps:
1. Begin by dividing -8 by 35: -8 ÷ 35 = -0.22857142857142856 (approximately).
2. Next, add 15 to the result: -0.22857142857142856 + 15 ≈ 14.77142857142857 (approximately).
Therefore, the simplified expression is approximately 14.77142857142857.
To simplify the expression -8 ÷ 35 + 15 using mental math, you can follow the order of operations (also known as PEMDAS or BODMAS).
1. First, evaluate the division, -8 ÷ 35.
When dividing a negative number (-8) by a positive number (35), the quotient will be negative.
So, -8 ÷ 35 = -0.22857142857 (approximately).
2. Next, add the result from step 1 to 15.
-0.22857142857 + 15 = 14.77142857143 (approximately).
Therefore, the simplified expression is approximately equal to 14.77142857143.
