### Mr. H's percent problem posting

The problem I found is this

In a certain class, the ratio of passing grades to failing grades is 7 to 5. How many of the 36 students failed the course?

Please post an answer by placing it in my comments.

Did you get the right answer?

The solution can be found here.

7=passing 5=failing

7:5

7+5=12

5 just failed so

5/12=.416 with the six repeating

5/12 x 36=15 failures

15 students are failures.

36 Students

7:5 = passing : failing

7+5=12

5 out of every 12 students failed

5/12 = .416 with 6 repeating

.416 with 6 repeating x 36 = 15

so, 15 students failed

5 diveded by 12= .416 with the six repeating

.416 with the six reapeting x 36 = 15

15 students failed

7+5=12

12x3=36
