Question

Do the ratio $2kg:80kg$ and $25g:625g$ form a proportion?

Answer 1

Solution:
Step 1 : Check whether the ratio form the proportion or not
In a portion, the first two terms(quantities) must be the same kind and of the same unit, whereas the last two terms (quantities) must also be of the same kind and the same unit.
Given, $2kg:80kg$ and $25g:625g$

$\therefore 2:80$ $=\frac{2}{80}$$=\frac{2}{2\times 40}$$=\frac{1}{25}$
$\therefore$ Ratio $2:80\ne$ Ratio $25:625$
Hence, they do not form the proportion.
