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
