Question

Can you figure out how many questions I need to get correct to past?

~80% or up to past
~300 points in total
~5 points per question
~60 questions in total

Answer 1

\(\sf \dfrac{80}{100} = \dfrac{x}{300}\)

Solve for 'x', can you do that?

Answer 2

Well, the common denominator is 300, and 300 / 100 is 3..so you can just multiply that to 80.

Answer 3

oh that is so easy

Answer 4

3 * 80? = 240

Answer 5

Correct..so you need at least 240 points to pass.

Since each question is worth 5 points, divide it by 5.

Answer 6

240 / 5 = 4

Answer 7

48

Answer 8

so 48 questions?

Answer 9

Yes..that's our answer.

Answer 10

thanks so much!

Answer 11

0.8 ( 60 ) = 48

Answer 12

You need to get 48 out of the 60 questions correct to have an 80%.

Answer 13

No problem.
