Question

evaluate : "-12/5" + 31/10 + 11/-15

Answer 1

Answer:

$\frac{ - 12}{5} + \frac{31}{10} + ( - \frac{11}{15} )$

Step-by-step explanation:

LCM of 5, 10 and 15 is 30

So,

-12/5×6/6 = -72/30

31/10×3/3 = 93/30

11/-15×2/2 = 22/-30

$\frac{ - 72 + 93 - 22}{30} = \frac{21 - 22}{30} = \frac{ - 1}{30}$

Answer. -1/30
