Why can unit ratios be helpful? (select all that apply)

• They sometimes convey more meaningful information

• They are always whole number ratios and look nicer

• They aren't

• They make it easier to compare two different ratios

Answer explanation

Unit ratios convey more meaningful information: Saying Person A driving 320 km in 4 hours is a lot less helpful than hearing Person A driving 80 km in one hour (80 km/hr)

They also make it easier to compare two different ratios. Like above: Who's faster? Person A or Person B driving 440 km in 6 hours? By converting to a unit rate (divide first term by second term) I see person B is going 73 km/hr and is slower than Person A
