Question

Harriet counts 15 big boxes and 12 small boxes of notebooks. Each large box contains 189 notebooks, and each small box contains 79 notebooks. Estimate the total number of notebooks. Is your estimate an overestimate or an underestimate? Explain why it is better to have an overestimate than an underestimate.

Answer 1

3783

Explanation:

Answer 2

I would round 189 to 190 and multiply by 15

190 *15 = 2850

I would round 79 to 80 and multiply 80x 12 = 960

2850 + 960 = 3810 notebooks ( estimated)

actual totals: 15*189 = 2835

12*79 = 948

2835 + 948 = 3783

this estimate was high

depending on the situation depends on if it is better to over estimate or under estimate
