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 รท .55 which is 60.
Therefore, 33 is 55% of 60.
