Question

NEED HELP FAST PLEASEEE!!!! When Talia performs in a cheerleading competition she makes 2 mistakes

in every 3 minutes of performance. If she performs for a total of 18
minutes in the competition tonight, how many mistakes will she
make?
A. 12
B. 15
C. 16
D. 27
E. 30

Answer 1

(A) 12

Explanation:

This is actually very simple!

If Talia makes 2 mistakes every 3 minutes then the ratio is 2:3

Going along with that if you know how ratios work then that should be easy. But this is also the long way. You dont really need to know ratios you just need to know the steps but knowing ratios would be helpful.

You first divide

18 / 3 = 6

Then multiply

6 x 2 = 12

That's it!

Hope this helped! :)
