Mr. George divided his money in the ratio 2:6 between Evan and ricky. Evan got the smaller amount of $420. How much did ricky receive

Ratios are like fractions in the way that you can simplify them if they have common factors.

we can simplify this ratio to

1:3

that means that the bigger part got 3 times the amount of the smaller part. The problem says that Evan got the smaller amount, so if we multiply the smaller amount by 3 we should and will get the bigger amount. It says that $420 is the smaller part.

420*3=1260

so the bigger amount of money is $1260

So, because Ricky got the bigger part of Mr. George's money, he must have received

$1260
