Question

The number 3.12{bar on 12} in the form p/q is

Answer 1

Answer:

Let a = 3.12 bar

Multiply both sides by 100,

= > 100 * a = 100 * 3.12 bar

= > 100a = 312.12 bar

Now subtract a from 100a,

= > 100a - a = 312.12 bar - 3.12 bar

Then, bar gets cancelled,

= > 99a = 312 - 3

= > 99a = 309

= > a = 309 / 99

= > a = 3.12 bar = 309/99

Therefore,

3.12 in p/q form is 309/99.

Answer:

answer = 309/99 = 103/33
