Answer 11

In a survey, of 15 people, 6 preferred ranch dressing on their salad. What percent preferred ranch dressing?

Answer 12

Okay so for this one you basically want to turn 6 out of 15 into a percent. What do you think?

Answer 13

hmm let me think.

Answer 14

I don't understand what your saying. 6 'out of' 15

Answer 15

Is it 2.5?
Because 6x2.5 is 15.

Answer 16

Okay so within 15 people we have 6 people who want ranch right?
Now we call that 6 out of 15 people want ranch.
So to turn that 6 out of 15 people first try dividing 6 by 15.

Answer 17

0.4

Answer 18

Okay now try turning 0.4 into a percentage.

Answer 19

40%

Answer 20

Correct so your answer is 40%.
