To find the ratio of muffins to donuts, you can set up the ratio using the numbers given. The bakery has 32 muffins and 56 donuts.
The ratio of muffins to donuts is:
\[ \text{Ratio} = \frac{\text{number of muffins}}{\text{number of donuts}} = \frac{32}{56} \]
Next, we can simplify the fraction by finding the greatest common divisor (GCD) of 32 and 56, which is 8.
So, we divide both by 8:
\[ \frac{32 \div 8}{56 \div 8} = \frac{4}{7} \]
Thus, the ratio of muffins to donuts is 4 to 7.
The answer is: A. 4 to 7
