Simplifying Fractions 4

Ten fractions, one task: shrink each one down to its lowest terms. If you've been building up your simplifying skills, this set keeps the momentum going with denominators in the teens. A couple of the prompts you'll see are 9/15 and 4/16, and the trick each time is finding the largest number that divides both parts cleanly.

One thing worth noticing: some fractions reduce in a single step while others need two or three. 12/16, for instance, lands on three quarters. Spotting that bigger common factor early saves you a lot of time. Recommended level: beginner to intermediate.
