Ann and Betty shared a sum of money in the ratio 2:3 respectively. Ann received $120. What is Betty's share?

One way to approach this would be to count the number of parts in the ratio: It's 2 + 3 = 5. Then Ann's share is 2/5 of the total amount. Betty's is 3/5. Your job is to determine the amount of $ that they split up, and what Betty receives as her share. Let x = the amount the girls split up. so if $120 is 2/5 then 60 is 1/5 so 60*5 = 300

Betty's share is 120 divided equally.
