Answer:
12 students.
Step-by-step explanation:
The complete question would be:
If ice cream is the last dessert, then we can solve for how many percent of the students like ice cream. If we add the 4 desserts percent, it should be equal to 100%
Pie : 15%
Candy : 23%
Cake : 27%
Pie% + Candy% + cake% + ice cream% = 100%
15% + 23% + 27% + Ice cream% = 100%
65% + Ice cream% = 100%
Ice cream% = 100% - 65%
Ice cream % = 35%
Percent is a way of saying how many out of a 100. Before we can tell how many students like pie, we need to figure out how many students were surveyed.
It says here that 35% of them like ice cream and among the students, 28 students like ice cream. This means that 28 is 35% of a number, which will be the number of students surveyed.
So as a fraction:
We need to find a ratio that is proportional to that, with 28 as the part of the whole.
So that is the number of students survey. Now to look for how may people like pie, we find what is 15% of 80. So we find the part of the whole this time:
