Three consecutive numbers whose sum is 12 are _________, _________ and _________. Fill in the blanks to make the statement true.

Solution:

Given, three consecutive numbers whose sum is 12 are _________, _________ and _________.

We have to fill in the blanks to make the statement true.

Let the three consecutive numbers be x , x + 1 and x + 2.

According to the question,

x + x + 1 + x + 2 = 12

On grouping of common terms,

x + x + x = 12 - 1 - 2

3x = 12 - 3

3x = 9

x = 9/3

x = 3

Now, x + 1 = 3 + 1 = 4

x + 2 = 3 + 2 = 5

Therefore, the three consecutive numbers are 3, 4 and 5.
