14 of her savings while Risa used
38 of her savings. What fraction of their total savings was used to buy the gift?
Each girl shared half the cost of the gift. The amount that each of them spent is the same.

14 of Wendy's savings =
38 of Risa's savings
312 of Wendy's savings =
38 of Risa's savings
