Answer 1

Answer:

The difference of $-1\frac{2}{5}-(-\frac{4}{5})$ is $\mathbf{\frac{-3}{5} }$

Step-by-step explanation:

We need to find the difference of: $-1\frac{2}{5}-(-\frac{4}{5})$

First of all convert mixed fraction into improper fraction

$-1\frac{2}{5}-(-\frac{4}{5})\\=\frac{-7}{5} -(-\frac{4}{5})$

Now, we know that negative sign multiplied by negative sign is positive i.e.  -(-)=+

So, we get:

$=\frac{-7}{5} +\frac{4}{5}$

For solving fractions, we need to take LCM of denominator.

LCM of 5 and 5 is 5

$=\frac{-7*1+4*1}{5}\\=\frac{-7+4}{5} \\=\frac{-3}{5}$

So, the difference of: $-1\frac{2}{5}-(-\frac{4}{5})$ is $\mathbf{\frac{-3}{5} }$
