Question

the mean proportion between 12 and 48 is​

Answer 1

GIVEN: To find the mean proportional between 12 and 48

SOLUTION:

let x be the mean proportional between 12 and 48

x:12::48:x

x/12=48/x

By cross multiplication we get,

x²=576

To remove the square from x, we have to taki square root on both sides

√x²=√576 (576=2²X2²X2²X3²)

x=24

Result: x=24

Hence, the mean proportional between 12 and 48 is 24.
