Arope is cut into 3 pieces, p, q, and r. the lengths of the pieces are in ratio 3: 5: 7. if the rope is 33feet 9 inches long find the lengths of p, q and r

3:5:7
3+5+7=15
15 units

33ft 9in =15 units
convert to feet
33ft=12in times 33=396in
396+9=405

405in=15units
divide both sides by 15
27=1unit

p=3units
p=3*27
p=81 inches=6ft 9in

q=5 units
q=5*27
q=135 inches=11ft 3in

r=7units
r=7*27
r=189 inches=15ft 9in

p=6ft 9in
q=11ft 3in
r=15ft 9in

Im not that good with division but i think 5 is -6but dont quote me on thatim not the best in division but thats my answer
