Question

The ratio of breadth and length of a hall is 2 : 5. Complete the following table that shows some possible breadths and lengths of the hall.

Answer 1

Given the ratio of breadth and length of the hall = 2 : 5.

Also given breadth of the hall = 10

length of the hall = 25.

Ratio of breadth : length = 10/25 = 2/5 = 2:5

To find First missing number:

Take the first ratio = 2/5 = (2×10)/(5×10) = 20/50

First missing number = 20.

Also, 2/5 = (2×20)/(5×20) = 40/100

Second missing number = 100
