Answer:
8 months
Step-by-step explanation:
Each month it grows 1/4 of an inch, or if x represents months, we could say:
1/4x
We know that it got a total of 2 inches taller, so we can set the expression above equal to 2
1/4x=2
To solve for x, we need to get x by itself. Divide both sides by 1/4, or multiply both sides by the reciprocal of 1/4.
The reciprocal is the numerator and the denominator switched, 1/4-->4/1
4/1*1/4x=2*4/1
x=8
So, she was measuring for 8 months
