1. Sarah ran 3,516 m yesterday on the track at her school. One time around the track is 293 m. Sarah wants to run 4,993 m today. Which number sentence can be used to calculate how many laps around the track Sarah should run today?
n = 4,993 ÷ 293
3,516 ÷ 293 = n
n = 4,993 - 293
4,993 - 12 = n

@trackzz could you help me with this one?

anonymous · Answer

1 lap = 293m so you can write it like this:
$$\frac{1lap}{293m}$$
If you want to convert from 4993m to laps, then you can try to match the units:
$$4993m*\frac{1lap}{293m}$$
Notice how the two meter units cancel out and you're left with the lap unit.
