Question

Are the following in proportion?

$\frac{2}{6}and\frac{8}{12}$

Answer 1

Step-1: write in the form of $\frac{a}{b}=\frac{c}{d}$

Here, $a=2$ $b=6$ $c=8$ and $d=12$

Four quantities a, b, c, and d are said to form a proportion if $\frac{a}{b}=\frac{c}{d}$

Step-2: check whether $a\times d=c\times b$or $not$

$a\times d=2\times 12=$$24$

$c\times b=6\times 8=$$48$

Here, $48\ne 24$

$a\times d\ne c\times b$

Hence, $\frac{2}{6}and\frac{8}{12}$are not in proportion
