Answer 1

1) 8.5

2) 60

3) 69.3

4) 6.8

5) 3.6

6) 10.5

Explanation:

Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value, 6.9 x 40 = 276.0 or 276)
