Answer:

The first common multiple is 60

Step-by-step explanation:

The first common multiple can be found by making a list of multiples of each number and finding the first one that is the same:

12x1=12

12x2=24

12x3=36

12x4=48

12x5=60

15x1=15

15x2=30

15x3=45

15x4=60

Notice that 12x5=60 and 15x4=60

This is the first multiple they have in common, therefore 60 is the first common multiple.
