Can someone walk me through the steps: Steve increases his math average by 9 points over a period of 15 weeks. How many points p

ozzi

hmmm units rates are just a matter of one above the other.

in this case is points/week.

9/15 points/weeks, we can just divide 9 ÷ 15 = 0.6, or 3/5.

so 0.6 points/weeks.
