Answer 1

Answer:

$\huge\underline\bold\red{Answer}$

Let the number be x

According to the question

$\frac{ - 5}{7} + x = \frac{ - 2}{3}$

$x = \frac{ - 2}{3} + \frac{5}{7}$

$x = \frac{1}{21}$

Hence, the required number = 1/21

Answer 2

Answer:

let the no. be x

-5/7+x=-2/3

x=-2/3+5/7

lcm of 3 and 7=21

x=-2×7/3×7 + 5×3/7×3

x= -14/21 + 15/21

x= 1/21
