Question

Express each of the following ratios in its simplest forms:
$\left(v\right)$ $2.5:1.5$

Answer 1

Find the simplest form of given ratio
We have,
$2.5:1.5=\frac{2.5}{1.5}$
Above ratio or fraction can be converted to its simplest form by dividing numerator and denominator by $10$, we get
$\frac{2.5}{1.5}=\frac{2.5\times 10}{1.5\times 10}=\frac{25}{15}$
Now, Further above ratio or fraction can be converted to its simplest form by dividing numerator and denominator by $5$, we get
$\frac{25÷5}{15÷5}=\frac{5}{3}$

Therefore, the simplest form of $2.5:1.5$ is $5:3$.
