Q6 What should be added to -7/8 so as
to get 5/9 ?
​

Answer 1

Answer:

$\frac{103}{72}$

Step-by-step explanation:

Let the number to be added be x

:.

$- \frac{7}{8} + x = \frac{5}{9} \\ x = \frac{5}{9} + \frac{7}{8}$

LCM of 8 and 9 = 72

:.

$x = \frac{(5 \times 8) + (7 \times 9)}{72} \\ = \frac{40 + 63}{72} \\ x = \frac{103}{72}$
