At a school pep rally the ratio of students who wore red to those who wore yellow is 7 to 3 their are 300 students at the rally
each wore either red or yellow how many more students wore red???
1 answer:
Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow
and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow
how many more wore red.....(210 - 90) = 120 more students wore red then yellow
