<human>:  Carly had 42 lollipops to share with her friends. Half of the lollipops were cherry, and the rest were equal amounts of watermelon, sour apple, and grape. How many lollipops were grape?
<bot>: How many lollipops were not cherry? ** Of her 42 lollipops, half were cherry, so 42 lollipops / 2 = <<42/2=21>>21 were not cherry.
How many lollipops were grape? ** Of the 21 that were not cherry, 1/3 of them were grape, so 21 lollipops / 3 = <<21/3=7>>7 grape lollipops.
