Answer:
In order to solve this, we must first transform the percentage into a decimal. We can do this by either dividing it by 100, or (my personal shortcut) just shifting the decimal point over 2 places to the left.
36% = 0.36
Now, we just divide 18 by the decimal to find out what the original number was.
18 / 0.36 = 50
So 36% of 50 is 18.
Let's check our work. To check, we just need to multiply 0.36 * 50, since the word 'of' in mathematics always implies multiplication.
0.36 * 50 = 18
So our work was correct. 36% of 50 is 18. Hope that helped =)
