Question

Express the following in the terms of ratios. 

i) The length of a rectangle is 5 times to its breadth. 

ii) For preparing coffee, 2 cups of water require to 1 cup of milk.

Answer 1

i) Let the breadth of rectangle = x = 1 part 

length of rectangle = 5x = 5 parts 

Ratio = length : breadth = 5x : x = \(\frac{5x}{x} = \frac{5}{1}\) = 5 : 1

ii) To prepare coffee, 

Required cups of water = 2 

Required cups of milk = 1 

Ratio = water : milk = 2 : 1
