Answer:
15/4
Step-by-step explanation:
This is because the denominator is 4 which means that there has to be 4 above it to make one:
4/4=1
So, with that being said, we do 4x3 = 12
But then we add 3 to the numerator(top number of the fraction) because the starting equation was:
3 3/4 = 15/4
Hope this helps!
Have a great day! :)
