Question

Lisa has a rope that measures 9 1 4 feet in length. She will cut the rope into pieces that are each 3/4 foot long. How many full pieces can Lisa cut from her rope, and how much of her rope will be remaining?

Answer 1

Divide the whole (914 feet) by the size of the pieces (3/4 foot)

x= number of 3/4 foot pieces

x= 914 feet ÷ 3/4 foot pieces

*Multiply by 3/4 reciprocal (inverse)

x= 914 * 4/3
x= (914*4) / 3
x= 3656/3
x= 1218.66
x= 1218 whole pieces and 66/100 is left over.

There are 1218 foot sized pieces. There is 66/100 foot left over (or 0.66 foot left - not rounded). If you round to the tenths, it's 7/10 foot left.

Hope this helps! :)
