First convert 1 1/4 into a improper fraction:
5/4
Then convert 3 1/2 into a improper fraction:
7/2
Now find the LCM of both denominators:
4
Now multiply the fractions such that the denominators are equal to 4:
5/4 x 1/1 = 5/4
7/2 x 2/2 = 14/4
Now add the numerators:
5 + 14 = 19
Now put the numerator and denominator together to get:
4 3/4
1 1/4 +3 1/2 =
5/4 + 7/2=
5/4 + 14/4=
19/4= 4 3/4
