3/8 + 2/3 = 1 1 1/24
9 + 4 = 13
1 1/24 + 13 = 13 1/24
13 1/24 is the answer, we must make it a improper fraction.
First multiply the denominator by the whole number, so 24 x 13, then add the sum to the numerator (d x w + n)
So 24 x 13 is 312 + 1 = 313
Then let's copy the denominator
So the answer is 313/24
