4:5=36:m
You asked:
Solve \(4 : 5=36 : m\) for the variable \(m\).
MathBot Answer:
$$\begin{aligned}m &= 45\end{aligned}$$
Express both ratios as fractions. \[\frac{4}{5} = \frac{36}{m}\]
Cross-multiply and solve for the unknown. $$\begin{aligned}\frac{4}{5} &= \frac{36}{m} \\ 4 m &= 180 \\ m &&= 45 \end{aligned}$$
