Question

1.4/7`in simplest form

Answer 1

$\dfrac{1.4}{7}=\dfrac{1.4\cdot10}{7\cdot10}=\dfrac{14}{70}=\dfrac{14:14}{70:14}=\dfrac{1}{5}$

Answer 2

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.
