Answer 1

Answer: Let the no. be x

Then A.T.Q.: -5/7 - x = -1

= -x = -1 + 5/7

= -x = -2/7

x = 2/7.

Answer 2

Answer:

2/7

Step-by-step explanation:

Let the no. be $x$

According to question,

$\frac{-5}{7} -x=-1\\\\x=\frac{-5}{7} +1$

$Taking$  $LCM,$

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

Hence, 2/7 should be subtracted to get -1
