Question

A bag contains 24 blue marbles, 32 yellow marbles, 43 white marbles, and 21 red marbles.

If a marble is drawn from the bag and replaced 90 times, about how many times would a yellow marble be drawn? A. 15 B.24 C.30 D.60

Answer 1

The answer would be B
Steps 
1. Add all the numbers 43+24+32+21

2. You should get 120

3. 120 will be your denominator

4. Determine how many yellow marbles there are, there are 32

5. Simplify 32/120 you should get 4/15, I simplified by 2 to get the answer, I simplified until I could simplify no more

6. Now change 4/15 to a decimal

7. To do step 6 you must divide 4 by 15

8. you should get0.26666666666

9. Now multiply 90*0.26666666666

10. You should get 23.9

11. round 23.9 by tenth place

12. You should get 24 thats how the answer is B
