Question

Convert each part of the ratio to percentage.
$1:4$

Answer 1

Given ratio

$1:4$

Let $x$ be the common ratio

$\therefore$ $x$ and $4x$ are parts

% of first part $=(\frac{x}{x+4x}\times 100)$

$=\frac{1}{5}\times 100=20$%

% of second part $=(\frac{4x}{x+4x}\times 100)$

$=\frac{4}{5}\times 100=80$%
