To find out how much the student weighed in fourth grade, we can use the given information that he currently weighs 90 pounds, which is 120% of what he weighed in fourth grade.
First, we need to determine what portion of his current weight represents 100%. We can do this by dividing his current weight by 120% (or 1.2).
90 pounds ÷ 1.2 = 75 pounds
Therefore, the student weighed 75 pounds in fourth grade.
