Answer:
81
Step-by-step explanation:
Multiply 90/100 with 90 = (90/100)*90 = (90*90)/100 = 81.
i got 100. not sure how the other guy got 81, but what i did is compare it to a test score or a discount. if you have a total of 100 possible points on the test with every question worth 10 points and i got 9 questions right, i got a 90 percent.
let's say a shopping discount. If you got a 90% discount for a item with original price of $100, it costs $10 with "90" being the amount you took off
if 100 isn't right, i honestly have no clue lol. good luck though
