Question

Jackson bought 5 ounces of raisins for $4. How much could he have buy for 1$?

Answer 1

Answer:

x=   1 1/4 ounces

Step-by-step explanation:

We can use a proportion to solve this problem.  Put the cost over the number of ounces.

$4                  $1

----------    = ---------------

5 ounces       x ounces

Using cross products

4x =1*5

Divide each side by 4

x =5/4

x=   1 1/4 ounces

Answer 2

If you do 5 divide by 4 then you can find what 1$ would be worth so ie.
5 divide by 4 is 1.25 which means that for 1$ you could buy 1.25 ounces
