You would do: 

1) Find the amount that it has increased by subtracting old from new number 
26-18= 8

2) Take your old number/ original number (18) and divide it into 8.
8/18= 0.44... (repeats 4 FOREVER) 

3) Multiply 0.44 by 100 to get a percent. 
0.44*100= 44  (round to the nearest whole) 

4) Final answer= 44%
