Question

Check whether the given terms $12,16,6,8$ are in proportion.

Answer 1

Four quantities $a,b,c$ and $d$ are said to be in proportion if $a:b=c:d$

or $\frac{a}{b}=\frac{c}{d}$

Here given quantities are $12,16,6,8$

$$\begin{gathered} 12:16=6:8 \\ \frac{12}{16}=\frac{6}{8} \\ \frac{3}{4}=\frac{3}{4} \end{gathered}$$

Since, ratio of first two term equals to the ratio of last two terms.

Hence, given terms $12,16,6,8$ are in proportion
