Explanation
Step 1
find the proportion of meat pieces and vegetable pieces
[tex]\text{ratio}=\frac{2}{11}[/tex]in other words, for every 2 pieces of meat the pizza has 11 pieces of vegetable
or , 2 of the 13 pieces are meat
and
11 of the 13 pieces are vegetables
so, the proportions are
[tex]\begin{gathered} \text{Proportion vegetables=}\frac{11\text{ }}{13} \\ \text{Proportion of meat= }\frac{2}{13} \end{gathered}[/tex]Step 2
Multiply each proportion by the number of pieces to find the number of pieces
[tex]\begin{gathered} Number\text{ of pieces of meat=39}\cdot\frac{2}{13}=6 \\ \text{Number of pieces of vegetable=39}\cdot\frac{11}{13}=33 \end{gathered}[/tex]so
Meat pieces:6
Vegetable pieces:33
