Answer 1

Answer:

In a bag full of small balls, 1/4 of these balls are green, 1/8 are blue, 1/12 are yellow and the remaining 26 white. How many balls are blue?

Solution

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) = 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.
