Question

convert 0.4 (on 4 bar) into rational form?​

Answer 1

Answer:

4/9

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.
