So we wan't to know what is the sum of 3 2/3 and 14 2/5. First lets turn them into fractions: first one is 11/3 and the second is 72/5. Now lets add them: We multiply fractions this way: (a/b)+(c/d)={(ad)+(cb)}/(bd). Following this rule: {(115)+(723)}/(35)={55+146}/15=201/15. and finally lets turn it back into a mixed number: 13 6/15
