$\bf \textit{so there are }2\frac{7}{9}\textit{ sections of land each one is }2\frac{1}{5}$

how much land are they all in total? well, is just their product.

let's firstly convert the mixed fractions to "improper" and then multiply.

$\bf \stackrel{mixed}{2\frac{7}{9}}\implies \cfrac{2\cdot 9+7}{9}\implies \stackrel{improper}{\cfrac{25}{9}}
\\\\\\
\stackrel{mixed}{2\frac{1}{5}}\implies \cfrac{2\cdot 5+1}{5}\implies \stackrel{improper}{\cfrac{11}{5}}
\\\\\\
\cfrac{25}{9}\cdot \cfrac{11}{5}\implies \cfrac{25}{5}\cdot \cfrac{11}{9}\implies \cfrac{5}{1}\cdot \cfrac{11}{9}\implies \cfrac{55}{9}\implies 6\frac{1}{9}$

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.She also earns a base salary

Ber [7]

From the information we have, we know the commission is at 7.25% of all she sells. So we first calculate this from total amount sold.

x =7.25/100 * 4,500

Where x is the commission earned.

x = 7.25 * 4,500 / 100

x = 7.25 * 45

x = 326.25

So commission earned is 326.25 $
