Which of the following options is the closest estimate to nearest tens for the following calculations:82 – 14 + 56
A. 130 B. 140 C. 120 D. 20
Answer: C
Solution: Let’s calculate the result of the given expression:
82 – 14 + 56 = 68 + 56 = 124
Now, we need to find the closest estimate to the nearest tens for 124. The tens place digit is 2, which is less than 5. Therefore, the closest estimate to the nearest tens is 120.
