Answer:

Step-by-step explanation:

Remark

The ratio you would use is 7 to 2 to 11

The question is what you you have to multiply these ratios by so the products when added come to 100?

Equation

7*x + 2*x + 11*x = 100        Combine the terms on the left

Solution

20x = 100                           Divide both sides by 20

20x/20  = 100/20              

x = 5

  • Red: 7 * 5 =    35
  • Green: 2 * 5 = 10
  • Blue: 11*5 =     55
  • Total               100

Answer: 55 blue marbles were in the bag.
