Question

give an example of how to find the fourth value in a proportion when 3 values are already given​

Answer 1

Answer:

Let the fourth term = x

18:27::32:x18:27::32:x

\Rightarrow\ 18\times x=27\times32⇒ 18×x=27×32

⇒ x=27×32/18 (cancellation is in the attachment)

=3×16=48

Fourth term = 48
