Which situation follows this ratio?

30 red marbles and 18 green marbles

70 red marbles and 42 green marbles

51 red marbles and 85 green marbles

Answer 1

This is basically like creating equivalent fractions. Ratios are like fractions so you would need to find what choice is equal to \(\frac{3}{5}\).

Answer 2

ok.. so whats the answer.. sorry i really need to get this done fast

Answer 3

Okay, so with a 3 to 5 ratio, get a calculator and divide 3 by 5.
3 divided by 5 = 0.6

Then do the same with each of the given scenarios
30 divided by 18
70 divided by 42
51 divided by 85
9 divided by 24

Whichever one equals 0.6 is the same as 3:5

We can count out the first two, because they would be whole numbers. (x > 0.6)
So that leaves the last two.
Divide those two and figure out which one is equal to 0.6
