Question

18 pounds of flour is $10. How much is one pound of flour?

Answer 1

`5/9$`

Explanation:

Each pound will cost a value so that if the value was multiplied by `18` it will give us `10$` . We don't know the value of the pound so let's call it `x`.

`18x=10$`

Divide both sides by `18`

`(cancel(18)x)/cancel18=(10$)/18`

`x=10/18$`

`10/18$` is our answer

But we can simplify it by dividing both the numerator and the denominator by the highest common factor `2`

`(10-:2)/(18-:2)=5/9$`

Our final answer is `5/9$`
