Question

Please help):

Estimate the product of 408 - 52 by first rounding each number to the nearest ten.
A: 20,000
B: 460
C: 450
D: 20, 500​

Answer 1

Answer: 20500

Explanation:

Rounding 408 to the nearest ten will give 410. Since it is above 4, we'll add 1 to the 0 in the tens value and this will be 410.

Rounding 52 to nearest ten is 50.

Therefore, we'll multiply 410 by 50. This will be:

= 410 × 50

= 20500

Therefore, the correct option is D.
