3.127 in p/q form


I need in full explanation





​

Answer 1

Step-by-step explanation:

Let x=3.127

=3.12777....................................(1)

Multiply (1) by 100 we get

100x=312.777......................................................(2)

Multiply (1) by 1000 we get

1000x=3127.777..........................................................(3)

Substruct (3) by (2) we get

900x=2815

x= 2815/900

x= 563/180

Hence x=3.127 = 563/180
