9:65=25:n
You asked:
Solve \(9 : 65=25 : n\) for the variable \(n\).
MathBot Answer:
$$\begin{aligned}n &= \frac{1625}{9}\end{aligned}$$
Express both ratios as fractions. \[\frac{9}{65} = \frac{25}{n}\]
Cross-multiply and solve for the unknown. $$\begin{aligned}\frac{9}{65} &= \frac{25}{n} \\ 9 n &= 1625 \\ n &&= \frac{1625}{9} \end{aligned}$$
