The sum of three consecutive numbers is 126. what is the smallest of the three numbers?

15

Step-by-step explanation:

Well to find the least common multiply of ,

we make a table.

3 - 3, 6, 9, 12, 15, 18

5 - 5, 10, 15, 20

Then, by looking at the table we can tell that the LCM is 15.

So we make the 3 and 5, 15.

3*5 = 15

Whatever happens to the denominator happens to the numerator.

1*3 = 3

3/15

5*3 = 15

2*3 = 6

6/15

Now we can add 3/15 and 6/15

=9/15

simplified

3/5

Thus,

the LCM need to add 1/3 and 2/5 is 15.

Hope this helps :)
