Question

Express the following as Rational Numbers ..?

please explain it by explanation ​

Answer 1

Answer:

i)4/9

ii)2/9

Step-by-step explanation:

Let x be 0.4 bar  x = 0.4 bar ….(1) 

Multiplying both sides by 10,

we get  10x = 4.4 bar ….(2) 

Subtracting (1) from (2),

we get  10x – x = 4.4 bar - 0.4 bar

9x = 4 x = 4/9.

Thus, simplest form of 0.4 bar as a rational number is 4/9.
