Question

Express the following in the form of p/q
i) 4.045 ( bar on 45)
Plzz solve this for me

Answer 1

Answer:

let x=4.045 (bar on 45)

multiplying both sides by 10

10x=40.45(bar on 45)=1

multiplying both sides by 100

1000x=4045.45(bar on 45)=2

subtracting 1 from 2

1000x-10x=4045.45 - 40.45 (bar on 45)

990x=4005

x=4005/990

Hope it helps.

Answer 2

Answer:

89/22

Step-by-step explanation:

Let 4.045454545.... = x

Multiplying both sides by 10, we have 10x = 40.45454545....... - (eq.1)

Now, Multiplying both sides by 100, we have 1000x = 4045.454545..... -(eq.2)

Subtracting (eq.2) from (eq.1), we get

10x - 1000x = 40.45... - 4045.45...

-990x = -4005

x = 4005/990 = 89/22

Hence, 4.04545.... = 89/22
