Okay. We are given that 90∘=12 children.
Let's first solve for the mint portion. 45∘ is half of 90∘, so the number of children that like mint ice cream should also be half of the number of children who like vanilla, giving us 6 children who like mint ice cream.
Next, let's solve for the angle measure of the strawberry portion of the pie chart. We are given that 14 children voted for strawberry. I'm going to use ratios to solve this one.
12:14=90:x.
12x=1260.
x=105.
So the angle measure of the strawberry portion is 105∘.
Finally, let's solve for the number of children who like chocolate ice cream. 120 is 43 of 90, so the number of children who like chocolate ice cream should also be 43 of the number of children who like vanilla ice cream.
12×43=16.
Therefore, 16 children like chocolate ice cream.
Hope that helps!
