Question

I have a box which has 3 green, 9 blue, 4 yellow, 8 orange coloured cubes in it.

(a) What is the ratio of orange to yellow cubes?

(b) What is the ratio of green to blue cubes?

(c) How many different ratios can be formed, when you compare each colour to any one of the other colours?

Answer 1

Number of green cubes = 3

Number of blue cubes = 9

Number of yellow cubes = 4

Number of orange cubes = 8

(a) Ratio of orange to yellow cubes  

Number of orange cubes /Number of yellow cubes = 8/4 = 2/1 = 2 : 1

Ratio of orange to yellow cubes = 2 : 1

(b) Number of green cubes/Number of blue cubes = 3/9 = 1/3

Ratio of green to blue cubes = 1 : 3

(c) The ratios can be Orange : Yellow, Orange: blue, Orange : green, Yellow : Orange, yellow : blue, yellow : green, blue : green, blue : orange, blue : yellow, green : orange, green : yellow, green : blue. Thus 12 ratios can be formed.
