A cupcake weighs 3 1/2 ounces. How many cupcakes are there in a 20-ounce package

Answer 1

Use division:

20 ÷ 3.5

5.714

Now you cannot have 0.714 of a cupcake. So check your numbers.

Answer 2

Let N = the number of cupcakes in a package.

Each one weighs 3.5 ounces.

The whole package weighs 20 ounces.

The equation would be 3.5 * N = 20 (weight of each cupcake * the number of cupcakes in the package)

Divide both sides by 3.5

N = 5.714

But a package of cupcakes only has a WHOLE number of cupcakes, not 5 whole ones and .714 of the 6th cupcake. So our answer has to be limited to 5 cupcakes. (5 whole cupcakes)
