Find the third proportional to 240 and 120.
60
The third proportional to two numbers \(a\) and \(b\) is the value \(x\) such that \(a:b=b:x\), that is \(x=\frac{b^2}{a}\).
Here \(a=240\) and \(b=120\), so \(x=\frac{120^2}{240}=\frac{14400}{240}=60\).
Hence, the third proportional to 240 and 120 is 60.
