Answer:

The smallest value of the three numbers would be 9.

Explanation:

In order to find this, set the smallest number as x. Then you can set each of the next integers as x + 1 and x + 2. Now we can total all three numbers and set equal to 30 to solve for x.

x + x + 1 + x + 2 = 30

3x + 3 = 30

3x = 27

x = 9
