Answer 1

So 3/8 is the ratio of black marbles to total marbles

Answer 2

Option B.
total = 32 black 12 so it is 8/3

Answer 3

Answer 4

Medal and fan?! Thx

Answer 5

I don't think B is correct

Answer 6

B. there are 3 black and 5 white. 3*4=12 and 5*4=20.

Answer 7

Since 3/8 is the ratio of black marbles to the total, 3/5 is the ratio of black marbles to right

Answer 8

white*

Answer 9

No@Pawtpie it's B. I just did this and it was b

Answer 10

I'm sorry B looks correct

Answer 11

Each answer tells you a number of black marbles and a number of white marbles.
For each answer, add the number of black marbles and white marbles.
Then write a ratio of the number of black marbles to the total and compare with 3/8.

Answer 12

Throw me the medal?! Thx

Answer 13

yep i think its B too. if you divide both of the numbers 12 and 20 by 4 (the number of times they drew) it equals 3 and white and 5 black

Answer 14

*3 white

Answer 15

Example:
Choice A. 3 black & 8 white
Total is 3 + 8 = 11
Ratio of black to total is: 3/11 which is not 3/8, so A is not the answer.
Now do the same for the other choices.
