(ii)\frac{14}{-49}

(iii)\frac{-15}{35}

(iv)\frac{299}{-161}

Answers (4)

(i)\frac{-12}{-30}

\begin{aligned} \frac{-12}{-30} &=\frac{-12 \div 6}{-30 \div 6} \\ &=\frac{-2}{-5} \\ &=\frac{2}{5} \end{aligned}

(ii)\frac{14}{-49}

\begin{aligned} \frac{14}{-49} &=\frac{14 \div 7}{-49 \div 7} \\ &=\frac{2}{-7} \\ &=\frac{-2}{7} \end{aligned}

(iii)\frac{-15}{35}

\begin{aligned} \frac{-15}{35} &=\frac{-15 \div 5}{35 \div 5} \\ &=\frac{-3}{7} \end{aligned}

(iv)\frac{299}{-161}

\begin{aligned} \frac{299}{-161} &=\frac{299 \div 23}{-161 \div 23} \\ &=\frac{13}{-7} \\ &=\frac{-13}{7} \end{aligned}
