There are 12 marbles in the container.. then colored half of the marbles red.in the quarter of the marble is blue.in the rest of marble us green.. what us the fraction of green

Answer 1

1/2 = red
1/4 = blue
? = green

Since one whole is 1, then the sum of the fractions must be equal to 1.
1/2 + 1/4 + (green) = 1
green = 1 - (1/2 + 1/4)
green = 1 - (3/4)
green = 1/4
