I would write the missing variable as x. It's what everyone uses.
Anyway, 91 divided by x is 65.
The way we can do this is reverse 65 and x.
91 divided by 65 = x.

91 divided by 1.4 = 65
65 x 1.4 = 91

x (or ?) = 1.4

Blababa [14]

<h3>Answer:</h3>

$\huge\boxed{1 \frac{4}{5}\ \text{ft}}$

<h3>Explanation:</h3>

Change $\frac{1}{5}$ so that is has a common denominator. $\frac{1*2}{5*2}=\frac{2}{10}$

Make an equation. $\frac{7+7+2+2}{10}$

Add. $\frac{14+4}{10}$

Add. $\frac{18}{10}$

Divide both sides by 2. $\frac{9}{5}$

Convert to a mixed number. $1 \frac{4}{5}$
