A sixth grader weighs 90 pounds which is 120% of what he weighed in 4 th grade. How much did he weigh in 4th grade?

90x100=9000/120= 75 So he weighed 75lbs is this correct?

Yes.

Idk that’s why I came here

yes

To find out how much the sixth grader weighed in 4th grade, we need to find the original weight and not the current weight. The given information states that the current weight is 120% of the weight in 4th grade.

Let's use algebra to solve this problem:

Let x be the weight in 4th grade.

According to the information given, we know that:

90 pounds = 120% of x.

To find the original weight in 4th grade, we need to solve for x.

To solve for x, we divide both sides of the equation by 120% (or 1.2):

90 pounds / 1.2 = x

This simplifies to:

75 pounds = x

Therefore, the student weighed 75 pounds in 4th grade.
