In a bag of small balls 1/4 are green, 1/8 are blue, 1/12 are yellow and the remaining 26 white. How many balls are blue?  Choose the most appropriate option:
A) 8 balls.
B) 4 balls.
C) 7 balls.
D) 5 balls.
E) 6 balls.
Let us first find the fraction of green, blue and yellow balls   1/4 + 1/8 + 1/12 = 6 / 24 + 3 / 24 + 2 / 24 , common denominator   = 11 / 24 , add numerators   The fraction of white balls is given by   24 / 24 - 11 / 24 = 13 / 24   So the fraction 13 / 24 corresponds to 26 balls. If x is the total number of balls then   (13 / 24) of x = 26 balls   or (13 / 24) * x = 26   x = 26 * (24 / 13)=

<output>48</output>
48 , total number of balls   The fraction of blue balls is 1 / 8 of x. The number of blue balls is given by   (1 / 8) of 48= 6 balls. correct answer 6 balls.
