The ratio of red jelly beans to yellow jelly beans in a dish is 3.4. If Greg eats 3 red ones and 6 yellow ones, the ratio is 4.5. How many yellow jelly beans were originally in the dish?

Do you make 3.4 a fraction and 4.5 a fraction and times them? 3/6 TIMES 4.5 = 12/20 THEN SUBTRACT 6 yellow ones?

  • math -

    Ratios are written 3:4, not 3.4

    Initially,
    r/y = 3/4

    Later,

    (r-3)/(y-6) = 4/5

    Solve those two equations to get
    r=27, y=36
