Yolanda has 2 granola bars. Each serving is of a bar of granola.

RSB [31]

The model of the granola bars is an illustration of <em>ratios and proportions</em>.

The model that shows the total serving is model A

The given parameters are:

$\mathbf{Bars = 2}$

$\mathbf{Serving = \frac{2}{5}}$

So, the number of servings in both bars is:

$\mathbf{Total = Bars \div Serving}$

Substitute 2 for Bars and 2/5 for Servings

$\mathbf{Total = 2 \div \frac{2}{5}}$

Express as multiplication

$\mathbf{Total = 2 \times \frac{5}{2}}$

$\mathbf{Total = \frac{10}{2}}$

$\mathbf{Total = 5}$

The total number of servings is 5

The model that shows a total serving of 5 is model A (see attachment)
