Well, first of all, LCM means Lowest Common Multiple. So you have to write out the factors of each of the numbers. So that will be;
2= 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
5=5, 10, 15, 20
So now, you have to pick out the numbers that are common to both numbers. So;
10, 20
10 and 20 are the only common numbers. So you have to look for the lowest common number. And that is 10. So the LCM is 10.. Hope i helped. Have a nice day.
Answer:
D
Step-by-step explanation:
a.
20/2 = 10
0, 10, 20, 30, 40, 50
b.
32.4/4 = 8.1
0, 8.1, 16.2, 24.3, 32.4, 40.5
c.
8.8/4 = 2.2
0, 2.2, 4.4, 6.6, 8.8, 11
d.
10/3 = 3.3
0, 3.3, 6.7, 10, 13.3, 16.7
