Joanna Singleton · Answer 1

Marisa had rounded 3.48 to 4 and times it to 7.33 which she rounded to 8

In fact 3.48 is closer to 3 we know this since the. 48 of 3.48 s below. 50 if it was. 50 or above it would round to 4 but it doesn't the same applies to 7.33 so

it should be 3 x 7 = 21

Isis Rush · Answer 2

If Marisa is going to estimate, then she needs to round each number. If she rounds to the nearest ones place, then she should have rounded 3.48 to 3 and rounded 7.33 to 7.

3 x 7 = 21
