Question

Express the following in the form p/q where p and q are integers and q not equal to 0
Question: 0.453 bar on 53

Answer 1

Answer:

Step-by-step explanation:

let x=0.453                                    (let the number in bold be repeating)

10x=4.53                                         (  i)

1000x=453.53                                (  ii)

from (i) and (ii)

1000x-10x=453.53-4.53

990x=449

x=449/990

Answer 2

let x =0.453 and (bar on 53) equation 1

mutiply b/s by 10

10x=4.53 and bar on 53___equation 2

multiply b/s by 100

1000x=453.53(bar on 53)___equation 3

Subtract equation 2 from 3

1000x-10x=453.53-4.53(bar on 53)

990x=449

x=449/990
