Four out of 5 dentists recommend Sparkle toothpaste. What percent of dentists recommend sparkle toothpaste?
2 answers:
80% all you have to do is divide 4 by 5 (4/5) you could also think of it like a five question quiz. every question you get wrong it subtracts 20 percent since 20 times 5 is 100 (3/5=.60 or 60%)
Well, the fraction would be 80/100th's but if you wanted it simplified it would be 4/5th's. Hope I helped. :)
