Answer:
12 because you have to divide 105 by 9 2inch is 11.6666666... so you round up and get 12
C - 3 1/12
Get a common denominator
3*3 / 4*3 + 1*4 / 3*4
Simplifies into 9/12 + 4/12
Adds to 13/12.
12 goes into 13 1 time, leaving us with 1 1/12
Add the 1 to the 2 full cups that already existed in the original problem - 3 1/12
A scale factor of 1.25, also written as 1 1/4 should be used
