Answer:
3.75
Explanation:
multiply the mixed number at the front by 4, add that to the 3 in the numerator: 15/4
multiply the fraction by 25/25 to get it out of 100 and so not as to change the original fraction
375/100
simplify
3.75
this explanation was a little complicated so I apologize
you could also keep the mixed number at the front the same and repeat the 25/25 process with the 3/4
