Question

simplify the given equations

Answer 1

☆ANSWER:

Given:

(i) $\frac{ - 3}{4} + (\frac{ - 5}{14} )$

(ii)$- 6 \div 3 \frac{3}{5}$

A.T.Q:

(i) $\frac{ - 3}{4} + ( \frac{ - 5}{14})$

=> First, the LCM of 4 and 14 is 28.

=> $\frac{ - 3 \times 7}{4 \times 7} + (\frac{ - 5 \times 2}{14 \times 2} )$

=>$\frac{ - 21 + ( - 10)}{28}$

=> $\frac{ - 31}{28}$

(ii) $- 6 \div 3 \frac{3}{5}$

=> $- 6 \div \frac {18}{5}$

=> $\frac {-6}{1} \div \frac {18}{5}$

=> $\frac{-6}{1} \times \frac{5}{18}$

=> $\frac{5}{-3}$ (Ans)
