Answer:
[tex]7\frac{4}{5}[/tex] pounds
Step-by-step explanation:
Lets convert mixed number to improper fraction. It can be done by the rule shown below:
[tex]a\frac{b}{c}=\frac{(a*c)+b}{c}[/tex]
So, 4 and 1/3rd becomes:
[tex]4\frac{1}{3}=\frac{13}{3}[/tex]
Lets find cost of 1 potato if 4 weigh [tex]\frac{13}{3}[/tex] pounds.
[tex]\frac{\frac{13}{3}}{5}=\frac{13}{3}*\frac{1}{5}=\frac{13}{15}[/tex]
Now, 9 of them would weigh (9 times this):
[tex]\frac{13}{15}*9=\frac{39}{5}=7\frac{4}{5}[/tex]
