Solve by finding a common denominator.
1 1/3 + 3 1/4
To find a common denominator, we need to find the lowest common multiple (LCM) of the denominators, which in this case are 3 and 4.
The LCM of 3 and 4 is 12.
Now let's convert the fractions to have a denominator of 12.
1 1/3 = 4/3 (multiplied 3 to numerator and denominator to have a denominator of 12)
3 1/4 = 13/4 (multiplied 4 to numerator and denominator to have a denominator of 12)
Now we can add the fractions:
4/3 + 13/4
To add fractions, we need a common denominator, which is 12 in this case.
Rewriting the fractions with a denominator of 12:
4/3 = (4/3) * (4/4) = 16/12
13/4 = (13/4) * (3/3) = 39/12
Now we can add the fractions:
16/12 + 39/12 = 55/12
So, 1 1/3 + 3 1/4 = 55/12.
