Question

Subtract.

Answer 1

-2 4/7 is your answer

Answer 2

Answer: The required simplified mixed number is $-2\dfrac{4}{7}$

Step-by-step explanation:

Since we have given that

$-3\dfrac{2}{7}-(-\dfrac{5}{7})$

We need to solve this.

First we change the mixed fraction into improper fraction.

$3\dfrac{2}{7}=\dfrac{23}{7}$

So, it becomes,

$-\dfrac{23}{7}+\dfrac{5}{7}\\\\=\dfrac{-23+5}{7}\\\\=\dfrac{-18}{7}\\\\=-2\dfrac{4}{7}$

Hence, the required simplified mixed number is $-2\dfrac{4}{7}$
