Question

1.4/7`in simplest form

Answer 1

1.4 / 7
Multiply by ten to get rid of the decimal. So...
14/70
Then divide each by 2
7/35
But you can divide it again. So divide it by its greatest common factor, which is 7. So....
1/5.
1/5 is your final answer.

Answer 2

`(1.4)/(7)=(1.4\cdot10)/(7\cdot10)=(14)/(70)=(14:14)/(70:14)=(1)/(5)`
