Express in the form , where p and q are integers and q ≠ 0.

Let x = 0.6

Multiply by 10 on both sides,

10x = 6

x = 6/10

x = 3/5

So, the p/q form of 0.6 = 3/5

Let y =

Multiply by 10 on both sides,

10y =

10y – y = -

= 7.7777777……. – 0.7777777…………..

9y = 7

y = 7/9

So the p/q form of = 7/9

Let z =

Multiply by 10 on both sides,

10z =

10z – z = -

= 4.7777777…………. – 0.47777777……………………

9z = 4.2999

z ≈ 4.3/9

z = 43/90

So the p/q form of

= 43/90

=
