F:m:s=4:5:7
s=f+18 and from above we see s/f=7/4 so s=7f/4 now we can say:
f+18=7f/4
4f+72=7f
3f=72
f=24 and we know s=f+18 so
s=42
m/s=5/7 so m=42*5/7=30
So Frank got 24, Mary got 30, and Seth got 42.
Ooh I loved this stuff but I kinda forgot how to do it but I know you are supposed to multiply 2 times pi times times radius so then 2 times 3.14 times 2.6 = ... and pi times 22 =...
