What three consecutive integers equal 81

81 / 3 = 27 
so middle number  = 27
the other 2 are 26 and 28

answer
26, 27, 28 are three consecutive integers equal 81

The consecutive integers:  n, n+1, n+2

That sum to 81:

n+n+1+n+2=81  combine like terms on left side

3n+3=81  subtract 3 from both sides

3n=78   divide both sides by 3

n=26

So the three numbers are 26, 27, and 28.

Your answer should be 1/3. i hope i could ! good luck : )
