anonymous · Answer

need help on how to do it

anonymous · Answer

use a proportion
1 / 2/7 = 14/x
x = 14 * 2/7
x = 4

anonymous · Answer

maybe easier to try 
$$\frac{2}{7}=\frac{x}{14}$$
$$x=\frac{2\times 14}{7}=2\times 2=4$$ keep the variable in the numerator

anonymous · Answer

or put more simply, each inch represents 
$$\frac{2}{7}$$ of a foot, so 14 inches represents 
$$14\times \frac{2}{7}$$ of a foot
