Anita got 4 problems wrong on a test of 36 questions. what percent of the questions did she get correct

The answer would be about 89%

to solve this problem first you would have to subtract 4 from 36 to get 32 because you want to know how many she got right first.

so you put 32 over 36 (the number she got right over the total number of questions) and n (the number you don't know yet) over 100. that will be the percent.

next all you have to do is cross multiply 32 times 100 and 36n, to get 3200 and 36n.

now you have to divide 3200=36n by 36 so you get n by its self but you have to divide on both sides of the equal sign.

when you divide you will then get 88 with a lot of remainder 8's so you would just round up to 89.

finally you know n = 89% so she got 89% of her questions right.
