Question

please solve the question and show your work so 43x8 and 50x10 = 500 is it a. overestimated or b. underestimated please show how u got this and write a full explanation and tell me how your answer is right

Answer 1

43 is somewhat close to 50,
and 8 is close to 10.

So we're using 50x10 to estimate 43x8.

Since both 43 and 8 are smaller than 50 and 10,
the 50x10 will produce an over-approximation,
a value larger than what we want.

a. 50x10 is an overestimation.
