Explain how you would model 45.8 ÷ 4 using base-ten blocks.
Answer:
Explanation:
45.8 ÷ 4 is done in base ten blocks method
above figure shows how it was done
step 1:
4 is shared among 4 groups no ones left over
step 2:
5 tenths shared among 4 groups 1 tenths left over
1 tenths cannot be regrouped
so, converted to hundredths
18 hundredths shared among the 4 groups
4 shared among groups and 2 left over

The school in town is building a track around its football stadium.
The principal must decide whether to build a track with 6 lanes or 7 lanes.
A 6-lane track will be 28.68 feet wide, 28.68 ÷ 6 = 4.78
and a 7-lane track will be 28.98 feet wide. 28.98 ÷ 7 = 4.14
If all lanes are of equal width in each track,
4.78 – 4.14 = 0.64
the lanes in a 6-lane track than in a 7-lane track is 0.64
