Question

Find the

$\left(iv\right)$ Sub-triplicate ratio of $216:343$

Answer 1

Step: Find the Sub-triplicate ratio

Cube root of given ratio is the sub-triplicate ratio.

$\therefore$ Sub triplicate ratio = $\sqrt[3]{3216}:\sqrt[3]{3343}$

$=\sqrt[3]{36^3}:\sqrt[3]{37^3}$

$=6:7$

Hence, the sub-triplicate ratio is $6:7$.
