Answer :
The number of blue shirts needed to make Tina’s blue shirt collection a third of her entire collection is what we are looking for.
One fourth of 112 (total # of soaps in collection) is 28. Now, we’ll subtract this from the number making up a third of 112 to find how many more shirts Tina needs.
One third of 112 is 37.3 repeated. We can get an exact answer, or we can get an answer that fits in context. there cannot be 0.3333 repeats of a shirt. We’ll round down to 37 shirts. That is 9 shirts more than one fourth of 113, so Tina needs 9 more shirts.
