ANSWER:

7 1/12

Step-by-step explanation:

1 1/4+ 1 1/2+ 4 5/12

for easier solving add all the whole number first:

1+1+4=6

now add the fractions

1/4+1/2+5/12

common denominator=12

divide the common denominator by the existing denominator and multiply the answer to the existing numerator. The answer would be the numerator while the denominator would be constant at 12

1/4 would be = 3/12

1/2 would be = 6/12

5/12 would be= 5/12

add the numerator and copy the denominator

3/12+6/12+5/12= 13/12 or 1 1/12

1 1/12(sum of fractions) + 6 (sum of whole numbers)

=7 1/12
