Question

simplify -11by 30 - 8 by 15 + 7 by 6 + -2 by 5​

Answer 1

Answer:

0.13

Step-by-step explanation:

$= > - \frac{11}{30} - \frac{8}{15} + \frac{7}{6} + ( - \frac{2}{5} ) \\ \\ = > - \frac{11}{30} - \frac{16}{30} + \frac{35}{30} - \frac{12}{30} \\ \\ = > \frac{ - 11 - 16 + 35 - 12}{30} \\ \\ = > \frac{35 - 39}{30} \\ \\ = > - \frac{4}{30} \\ \\ = > - \frac{2}{15} \\ \\ = > - 0.13$

Answer 2

Answer:

$\large{\boxed{\boxed{\sf\frac{-4}{30}\:or\:\frac{-2}{15}}}}$

Step-by-step explanation:

$\huge\sf\frac{-11}{30}-\frac{8}{15}+\frac{7}{6}+\frac{-2}{5}$

⇒$\large\sf\frac{-11-16+35+-12}{30}$

⇒$\large\sf\frac{-11-16-12+35}{30}$

⇒$\large\sf\frac{-39+35}{30}$

⇒$\large\sf\frac{-4}{30}$

Or

⇒$\large{\underline{\sf\frac{-2}{15}}}$
