Answer:
John has 4 more blue marbles than Jane.
Step-by-step explanation:
The ratio of John marbles is 1.5.
Let x be Jane's red marble and 6 y be Jane's blue marble.
x+y=20
x/y=1.5
x=1.5y
1.5y+y=20
2.5y=20
y=8 Blue marbles
x=1.5y
x=1.5(8)
x=12 Red marbles
Jane has 8 blue marbles while John has 12 blue marbles.
