Chapter 4 - Decimals - 4.5 Dividing Decimal Numbers - 4.5 Exercises: 62

Answer

Each student would need to collect $\approx 5$ box tops per week.

Work Step by Step

We saw in Exercise #60 that each student needs to collect 182 box tops. To find out how many box tops each student would need to collect per week during 38 weeks, we divide: $~~~~~~~~~~4.7$ $38\overline{)182.0}$ $~~~~~~\underline{152}$ $~~~~~~~~~300$ $~~~~~~~~~\underline{266}$ $~~~~~~~~~~~34$ We can stop the division with the remainder of 34 because we only need to round to the nearest whole number: $4.7\approx 5$ Therefore, each student would need to collect $\approx 5$ box tops per week.
