Step-by-step explanation:

For the first one

you have to get rid of yards and feet so you would take

7yards/15feet and take it times 3feet/1yard, because there are 3feet in a yard and you are trying to get rid of the units, so by taking those times each other you get

21/15 and the units cross out

For the second one

you have to get rid of the feet and inches this time

6feet/18inches* 12inches/1foot

72/18 and again the units cross out

14
