Answer 1

Heya !!!

This is your answer......

Given :--

$- 2 \frac{9}{10} + ( - 5 \frac{4}{15} ) \\ = - 2 \frac{9}{10} - 5 \frac{4}{15} \\ = \frac{ - 29}{10} - \frac{79}{15} \\ taking \: lcm \\ = \frac{ - 87 - 158}{30} \\ = \frac{ - 245}{30} = \frac{ - 49}{6} \\ = - 8\frac{1}{6}$
Hence this is your answer.....

Hope it helps...

Answer 2

Heya,

-2 9/10 + (-5 4/15)

=> -2 9/10 -5 4/15

[Convert mixed fraction into improper fraction]

=> -29/10 - 79/15

[Take LCM of 10 & 15]

[LCM of 10 & 15 is 5 × 2 × 3 = 30]

=> -87-158/30

=> -245/30

=> -49/6

=> -8 1/6

Hope my answer helps you :)
