Question

Estimate 760 X 55 by first rounding each number so that it has only 1 nonzero digit.

Answer 1

48000

Explanation:

After rounding each number to the criteria stated, we get the question 800 * 60. Multiply the 8 and the 6 and add the same number of zeros that are there right now. this is 48 + "000" so 48000.
