$14 : 10 , 21 : 15 \text{ and so on}$

#### Explanation:

$\text{the ratio "7:5" is in "color(red)"simplest form}$

$\text{that is no other factor but 1 will divide into 7 or 5}$

$\text{to obtain equivalent ratios multiply 7 and 5 by the }$
$\text{same value}$

$7 : 5 = \left(7 \times \textcolor{red}{2}\right) : \left(5 \times \textcolor{red}{2}\right) = 14 : 10$

$7 : 5 = \left(7 \times \textcolor{red}{3}\right) : \left(5 \times \textcolor{red}{3}\right) = 21 : 15$

$\text{However, in using ratios we would look to use the}$
$\text{simplest form version, that is } 7 : 5$
