Answer: 60
Step-by-step explanation: To answer the question 33 is 55% of what number, we translate the question into an equation.
"33 is" that's 33 = 55% which we need to write as a decimal and we can do this by moving the decimal point 2 places to the left to get .55 and "of what number" means times x.
Now to solve for x, we isolate the x by dividing both sides of the equation by .55. On the right, the .55's cancel each other and we are left with x. On the left, we have 33 ÷ .55 which is 60.
Therefore, 33 is 55% of 60.
