Answer:
30 percent
Step-by-step explanation:
In a percentage, you first need a fraction. A fraction has 1) a part, and 2) the whole.
[tex]\frac{part}{whole}[/tex]
At her birthday party, she had 7 chocolate cupcakes, 9 vanilla cupcakes, and
14 strawberry cupcakes. In total, when you add 7 + 9 + 14, you get 30
cupcakes in total.
So, the whole is 30.
The question asks for vanilla cupcakes, so the part is 9 vanilla cupcakes.
Now, you have your fraction. [tex]\frac{9}{30}[/tex]
Next, to convert to a percent, you first need to divide.
9 ÷ 30 = 0.3.
To covert to a percent, you can multiply 0.3 × 100 = 30.
So the percentage of the cupcakes at Maria's birthday party that were vanilla cupcakes is 30.
