1500 people to part in a walkathon. 450 of them were school children. The rest are adults. What percentage of the participants were adults?

Respuesta :

70% of the people were adults 

First you subtract 1500-450 = 1050
Then you divide 1050/1500 = .7

the percentage would be about 65% because 25% is 375 and 50% is 750 75% is 1125 so it would be 62% -65%
