Question

Arthur wanted to estimate the value of $52.3 \div 0.11$, so he decided to round each of the numbers 52.3 and 0.11 to the nearest whole number before dividing. Arthur's plan failed badly. What would have been his estimate if he had rounded each of the numbers to its biggest decimal place (that is, 52.3 to the nearest ten and 0.11 to the nearest tenth) before dividing?

Answer 1

Rounding 52.3 to the nearest ten gives 50, while rounding 0.11 to the nearest tenth gives 0.1. Dividing 50 by 0.1 is the same as multiplying 50 by the reciprocal of 0.1, which is 10. So 52.3 ÷ 0.11 can be estimated as 50 × 10 = 500.

So the answer is 500!!!

Answer 2

500.

Explanation:

0.11 to the nearest whole number is 0 so that failed because you cant divide by 0.

52.3 to the nearest ten is 50 and 0.11 to the nearest tenth is 0.1 so the estimate would be 50 / 0.1

= 500 / 1

= 500.
