## Other aspects of ratios

Apart from the above stated facts, when 2 quantities tend to have same units their ratio is known as a dimensionless number. On the other hand, ‘rate’ turns out to be a quotient of the variables with different units. In terms of expressing a ratio, it is either separated by a colon that is [:] or by the division symbol.

## Ratio formula

### The formula for ratio when 2 variables such as ‘a’ & ‘b’ are given is as follows –

$$a\quad :\quad b \Rightarrow\frac{a}{b}$$

$$E.g. \quad 1) \quad\quad\quad\quad \frac{1}{4}\quad \times A=\frac{3}{5}\times \quad B \Rightarrow\frac{A}{B}=\frac{3}{5} \times \frac{4}{1}\Rightarrow\frac{12}{5}\Rightarrow12 \quad : \quad 5$$

$$2) \quad a\quad : \quad b\quad =15\quad :\quad 25\Rightarrow3\quad :\quad 5$$
