ReplyDeleteWhat is the least common multiple of 15 and 24?
15 = 3 * 5 and 24 = 2 * 2 * 2 * 3, Eliminate one of each of the common factors (3) and multiply the rest of the prime factors, LCM = 120
What is the least common multiple of 12 and 30?
12 = 2 * 2 * 3 and 30 = 2 * 3 * 5, Follow the same procedure as above, eliminate 2 & 3, LCM = 60

Distance = Rate * Time
Rate = Distance/Time
Time = Distance/Rate
