Question

Check whether the given terms $2,3,4,5$ 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 $2,3,4,5$

$$\begin{gathered} 2:3=4:5 \\ \frac{2}{3}\ne \frac{4}{5} \end{gathered}$$

Since, ratio of first two term not equals to the ratio of last two terms.

Hence, given terms $2,3,4,5$ are not in proportion
