Question

Express 4.3 (3 in recurring) in the form of p/q​

Answer 1

Answer:

Solution 1.)

Let a = 4.3 ( bar on 3) ------(1)

10a = 43.3 (bar on 3) ------(2)

On subtracting equation 1 from 2, we get

9a = 39

=> a = 39 / 9

=> a = 13/3

Solution 2.)

Let a = 2.37 (bar on 37) ------(1)

100a = 237.37 (bar on 37) ------(2)

On subtracting equation 1 from 2, we get

99a = 235

=> a = 235 / 99
