Question

5 potatoes weigh 4 and one third pounds. How many pounds do 9 potatoes weigh?

Answer 1

`7(4)/(5)` pounds

Explanation:

Lets convert mixed number to improper fraction. It can be done by the rule shown below:

`a(b)/(c)=((a*c)+b)/(c)`

So, 4 and 1/3rd becomes:

`4(1)/(3)=(13)/(3)`

Lets find cost of 1 potato if 4 weigh
`(13)/(3)` pounds.

`((13)/(3))/(5)=(13)/(3)*(1)/(5)=(13)/(15)`

Now, 9 of them would weigh (9 times this):

`(13)/(15)*9=(39)/(5)=7(4)/(5)`
