Question

Out of 30 questions, Ahmad answer 12 of them incorrectly. What percent of the questions did he answer correctly?

Answer 1

First, you would need to determine how many questions he got correct.
30 - 12 = 18

Next, you would need to create an equation for this problem. Let x represent the unknown percentage.

`(18)/(30)` =
`(x)/(100)`

Now, you would cross multiply.
30x = 1,800

The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x = 60

Ahmad got 60% of the questions correct.

I hope this helps!
