part d: how much rope will be left over?

part e: explain how you found your answer.

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

Step-by-step 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
