Answer:
76%
Step-by-step explanation:
Because there were 50 people present at his birthday, 50 will be our denominator. Only 38 people chose to eat it so that will be our numerator. 38 out of 50 people chose to have chocolate cake:
[tex]\frac{38}{50\\}[/tex] would be the fraction.
50x2 would be 100 and we need 100 to make it a percentage. We will multiply the bottom and the top by 2.
[tex]\frac{38}{50}[/tex] x 2 = 76/100 = 76%
76% of the people at the party picked chocolate cake.
