Answer:
3.75 or 3 3/4
Explanation
Ok the denominators aren't the same so were going to make them the same by them changing into the same number.
we can do thins by timesing 5 by 4=20 and 4 timesing by 5=20
So now that the denominators are the same we have to times 1 by 4 since it denominator was times by same thing with 3 except that only get times by 5.
1 x 4=4 and 3 x 5=15 so now our two fractions are 15/20 and 4/20
15 divided by 4=3.75 and there's our answer.
we get the .75 because it is 3 more so 3 4 x3 =12 that's where we get 3 and then there is 3 left and 3/4 of and 3/4=0.75 and then you combined them to make 3.75.
hope it helps have a great afternoon
