The model of the granola bars is an illustration of ratios and proportions.
The model that shows the total serving is model A
The given parameters are:
[tex]\mathbf{Bars = 2}[/tex]
[tex]\mathbf{Serving = \frac{2}{5}}[/tex]
So, the number of servings in both bars is:
[tex]\mathbf{Total = Bars \div Serving}[/tex]
Substitute 2 for Bars and 2/5 for Servings
[tex]\mathbf{Total = 2 \div \frac{2}{5}}[/tex]
Express as multiplication
[tex]\mathbf{Total = 2 \times \frac{5}{2}}[/tex]
[tex]\mathbf{Total = \frac{10}{2}}[/tex]
[tex]\mathbf{Total = 5}[/tex]
The total number of servings is 5
The model that shows a total serving of 5 is model A (see attachment)
