Answer:

Step-by-step explanation:

Think about your 10 and 15 times tables starting from 1, when you find two similar numbers that is your least common multiple. It is important not to mix this up with least common factor (which would be 5)

10:

2 * 10 = 20

3 * 10 = 30

4 * 10 = 40 etc etc

15:

2 * 15 = 30

3 * 15 = 45

The common number here is 30, it is the lowest common multiple

For this one you have to add all of the numbers. 5.5 plus 6.5 plus 4.5 plus 2.75 which equals to 19.25. Then you, 19.25/4=4.8125. All i did was turn the fractions into decimals to make it easier and do the math.
