How do you convert 8 yards and 6 yards to inches show how you got your answer

Use unit labels to keep everything straight.  You set up multiplication so that you cancel units that you don't want and introduce those that you do...

8yd(36in/yd)=288in

or

8yd(3ft/yd)(12in/ft)=288in

Conversion problems are easy if you remember to cancel units like numbers do...

Paranthesis first

15*6= 90  and 4*22= 44 then divide first so 44/2= 22 then add

22+90= 112

so your answer is 112
