Answer:

-26/7 is the correct answer

Answer 2

To subtract : $-3$ from $\frac{5}{7}$

Solution :  

• Subtraction is the arithmetic operation of taking off difference between two numbers.

• Subtraction rules for integers:

1. If two negative integers are to be subtracted then addition operation is performed and difference obtained has negative sign . i.e. $(-)-(-)=-$
2. If one negative and one positive integers are to be subtracted then operation performed is subtraction and difference obtained has sign greater obtained is negative integer. i.e.  $(-)-(+)=sign \ of \ greater\ integer$
3. If both positive integers are to be subtracted then operation performed    is subtraction and difference obtained has sign of greater number i.e.$(+)-(+)= sign \ of\ greater \ number$

• Therefore according to above rule we solve.

         $\frac{5}{7} - (-3 )\\=\frac{5+ 21}{7} \\=\frac{26}{7}$

Hence, $\frac{26}{7}$ is the answer.
