R=B
JarI
2+5=7=t
r/b=2/5
r/t=2/7
b/t=5/7
b/84=5/7
7b/84=5
b/12=5
b=60
t-b=r
84-60=24
r=24
24 red and 60 blue in JarI
JarII
r/b
9r/5b
r=b
9m+24=5m+60
m=9
m=mulitplier
9*9/9*5
81/45
81+24=105 red
60+45=105 blue
jarI
24red
60 blue
jarII
81 red jarII
45 blue jarII
81+45=126 in jarII answer
9/5
9*9=81
9*5=45
9/5=81/45
total red=105
total blue=105
answer 81 red+45 blue=126 marbles in jarII
