Find the ratio of the weights of a hippopotamus (1500 kg) to a rhinoceros (2100 kg)
\(5:7\)
\begin{aligned}H: R &=1500: 2100 \\&=\frac{15}{3}: \frac{21}{3} \\&=5: 7\end{aligned}
Find the ratio of the weights of an African bush elephant (6000 kg) to an Indian elephant (4000 kg)
\(3:2\)
\begin{aligned}A: I &=6000: 4000 \\&=6: 4 \\&=3: 2\end{aligned}
Find the ratio of weights of a mountain gorilla (190 kg) to a Kodiak bear (665 kg)
\(2:7\)
\begin{aligned}G: B &=190: 665 \\&=\frac{190}{5}: \frac{665}{5} \\&=38: 133 \\&=2 \times 19: 7 \times 19 \\&=2: 7\end{aligned}
Find the ratio of the weights of a leopard (90 kg) an African lion (240 kg) and a Siberian Tiger (360 kg)
\(3:8:12\)
\begin{aligned}L: A L: S T &=90: 240: 360 \\&=\frac{9}{3}: \frac{24}{3}: \frac{36}{3} \\&=3: 8: 12\end{aligned}
Find the ratio of lengths of an anaconda (8.5 m), a python (8 m) and a cobra (3.5 m)
\(17:16:7\)
\begin{aligned}A: P: C &=8.5: 8: 3.5 \\&=\frac{85}{5}: \frac{80}{5}: \frac{35}{5} \\&=17: 16: 7\end{aligned}
