What’s 1.4 as a fraction?

##7/5 = 1 2/5##

Recall…. A decimal is a way of showing fractions which have their denominators as powers of 10.

The 1st decimal place shows “tenths” ie ##1/10##

The 2nd decimal place shows “hundredths” ie ##1/100##

The 3rd decimal place shows “thousandths” ie ##1/1000##

In this case we have 1.4.

This means ##1 4/10##, which can simplify to ##1 2/5##

But we could also have seen the entire number as being in tenths..

##1.4 = 14/10 = 7/5 = 1 2/5##

The answer is the same. You can choose with format you prefer for the answer.
