The answer is 3 3/4
Here's how I got my answer:
Step 1: Split the numbers apart. Which leaves us with [tex] 4 + .75 [/tex]
Step 2: Find the greatest common factor between the two(25). Then divide it by 75 and 100. Which leaves us with [tex] 3/4 [/tex] (once simplified).
Step 3: Combine the whole number component with the fraction, which leaves us with our answer, 4 3/4
