Answer:
50,75,and 100 there's supposed to be a 20 too but it's not there but oh well
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
46/69 * 100
0.66666*100
which is 66percent
45 divided by 8 is 5 r. 5. You can write this like 5 5/8 too.
