Question

A four-unit class expects each student to dedicate 10 hours a week to studying for the course. How many hours should a student expect to study for a particular class that is worth six units?

Answer 1

Set up a proportion\[\huge \frac{ 4unit }{ 10hours }= \frac{ ? }{ ? }\]
what goes on the right side?

Answer 2

first find no of hour dedicated to one unit
that is = no of hoers dedicated / no of units

no of hour dedicated to one unit =10/4=5/2
for 6 unit multiply it with 6
=(5/2)*6=15 hr/week
