310 of her savings while Marion used
18 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.
Make the numerators the same. LCM of 3 and 1 is 3.
310 of Jane's savings =
18 of Marion's savings
310 of Jane's savings =
324 of Marion's savings
