Answer:3 7/12 m
so first you want to add the whole numbers first so 1 + 2 = 3
then you want to add the fractions but they are not the same so you need to convert them into the same fraction 1/4 and 1/3 can both be turned into 12ths so you need to multiply the numerator and the denominator by the same number so 4 x 3 and 1 x 3 for the other fraction it would be 3 x 4 and 1 x 4 to get 3/12 and 4/12 then you can add them together to get 7/12 then add the whole number 3 + 7/12 = 3 7/12
