There are thrice as many girls as boys at a school. If 35% of the girls and 45% of the boys

have already completed their holiday project, what percentage of the learners still needs to
complete their project?

4 answers

Not completed percent:

(b and girls not doee)/(b+g)

(.65g+.55b)/(b+g)

(.65g+.55*3g)/(3g+g)

g(.65+1.65)/(4g)

2.2/4=.55 or 55 percent not done
100-55=45
23% boy
IS 65% OF THE GIRLS AND 55% OF THE BOYS WHO STILL NEEDS TO COMPLETE THEIR PROJECT
