Question

A teacher wants to give each student 5/9 of a pizza if the teacher has 10 slice of pizza then how many students will she be able to hand out pizza to?

Answer 1

The teacher will be able to give 18 students pizza.

Explanation:

Since each student needs `5/9` of a pizza and the teacher has `10` slices, you can set `x` to be equal to the number of students able to eat pizza. Theoretically speaking, if you do `(10)/x` you will get the amount each student will be able to eat. Since we already know that this "unknown" amount is equal to `5/9`, we can set up our equation to be `10/x = 5/9`. Now, we simply cross multiply by multiplying `5` by `x` and `9` by `10`. This will give us `5x = 90`. Dividing both sides by `5` gives us `x = 18`. The final answer is 18 students.
