First, we'll have to make the denominators same, by finding the LCM of the denominators
LCM of 16,24
16 = 2 x 2 x 2 x 2
24 = 2 x 2 x 2 x 3
LCM = Common factors * Uncommon factors
= 2 x 2 x 2 x 3 x 2 = 48
-7/ 16 = -21/48. (multiply by 3/3)
8/24 = 16/48. (multiply by 2/2)
= -21/48 + 16/48
= (-21 + 16)/48
= -5/48
