Question

. Express 0.123 in the form P, where p. q are
9
integers and q *0.
​

Answer 1

Let x = 0.123 (bar)

_____________________

Multiply by 100,

100*x = 100*0.123 (bar)

100x = 12. 3(bar)

____________________________

As there is one number (3) under bar, multiply by 10

10 *100x = 10 * 12.3 (bar)

1000x = 123. 3 bar

subtract 100x from both sides,

1000x = 123.3 (bar)

-100x = -12. 3 (bar)

900x = 111 [bar will cancel]

x = 111/900.
