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:
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.
x 2 = 76/100 = 76%
76% of the people at the party picked chocolate cake.
For this case we have the following expressions:
and
Let:
(Integer m)
(Integer n)
By definition, an integer m is divisible by an integer n if the remainder of the division is 0. That is, there is an integer p such that:
Rewriting the expression we have:
So:
We cancel similar terms:
We check:
Answer:
If they are divisible
