Answer 1

The correct option is A $-1\frac{2}{5}$

Step 1: Write the number $-1.4$ as sum of whole number and decimal part.
$-1.4=-1+(-0.4)$

Step 2: Write down the expression $(-1-0.4)$ into mixed form.
$-1-0.4=-1-0.4\times \frac{10}{10}$
$=-1-\frac{4}{10}$
$=-1-\frac{2}{5}$
$=-1\frac{2}{5}$
Answer:
So, $-1.4=-1\frac{2}{5}$
