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! :)
