Question

express the following in the form of p /q where q is not equal to 0
0.bar4 +0.18bar​

Answer 1

Answer:

= > 0.4 bar + 0.18 bar

Let 0.4 bar = a

So,

= > 4.4 bar = 10a

= > 4.4 bar - 0.4 bar = 10a - a

= > 4/9 = a

Let 0.18 bar = b

= > 18.18 bar = 100b

= > 18.18 bar - 0.18 bar = 100b - b

= > 2/11 = b

= > 0.4 bar + 0.18 bar

= > 4/9 + 2/11

= > 62/99

Hence answer is 62/99
