Based on the survey, which park had the greatest percentage of blue butterflies?
Park P
Park Q
Park R
Park S

All you have to do is divide the blue butterflies by the total butterflies for each one and which ever one has the greatest decimal is the answer

- anonymous

Tell me what you get

For P I got 3.9? @taylorz115820

- anonymous

do \[21\div89\] not the other way around

- anonymous

0.23 @taylorz115820

- anonymous

you should get .23

- anonymous

Yes

- anonymous

now do that for the rest and tell me what you get

A) −24
B) −12
C) 11
D)12

- anonymous

ok so what do you do 1st?

- anonymous

Add 9 both sides? @taylorz115820

- anonymous

Yep

- anonymous

Then what do you do?

- anonymous

Flip the -3/4 @taylorz115820

- anonymous

Yes and multiply both sides by it

its actually -3/2

- anonymous

I got 1? @taylorz115820

- anonymous

Let me check

- anonymous

How did you get 1?

- anonymous

No not the answer it is for solving the -3/2 when I multiplied it @taylorz115820

- anonymous

you need to also multiply to the other side so do (-2/3)•-18

- anonymous

I got 12 will it be D the answer? @taylorz115820
