Explanation:

Step1: Identify mushroom pizza fraction

The mushroom pizza is divided into 10 equal - parts and 3 are shaded. So the fraction of the mushroom pizza eaten is $\frac{3}{10}$.

Step2: Identify pepperoni pizza fraction

The pepperoni pizza is divided into 10 equal - parts and 6 are shaded. So the fraction of the pepperoni pizza eaten is $\frac{6}{10}$.

Step3: Calculate total fraction of pizza eaten

To find the fraction of one whole pizza eaten, add the fractions of the two pizzas eaten. Since we are considering them in terms of one whole pizza, and the fractions have a common denominator of 10, we add the numerators: $\frac{3}{10}+\frac{6}{10}=\frac{3 + 6}{10}=\frac{9}{10}$.

Answer:

$\frac{9}{10}$
