2/3 of blank is 18

How do I solve this?

27

Step-by-step explanation:

It's asking '2/3 of what number is 18", we can set up an equation ...

(2/3) x = 18 where x represents the unknown number ... now solve for x

2x/3 = 18 (simplify the equation)

2x = 54 (multiply both sides by 3 to get rid of the fraction)

x = 27 (divide both sides by 2 to isolate the x value)
