Step-by-step explanation: Our first step in this problem is to find the least common multiple for 2 and 5. However, 2 doesn't factor and neither does 5. When finding the least common multiple, we are looking for factors that match up but since there are none, our least common denominator is simply 5 x 2 which is equal to 10.
