Answer 1

part A= 808/12 or 673/12 or 67 1/4

Explanation:

for part a you need to make all of the fractions have the same denominator and then you can add and in this case it is you would have 46/3+41/2+124/4 now you make them all have the denominator of 12 which will make you have

184/12+252/12+372/`12=808/12 or 673/12 or 67 1/4
