Twenty of the students in Hannah's class or 80% of the class, voted to have pizza for lunch every Wednesday. how many students are in Hannah's class

25

Step-by-step explanation:

If 20 students make up 80% of the class

Then 100% ( all of the students in the class ) will give 100 * 20 / 80

= 2000/80

= 25

Therefore, there are 25 students in Hannah's class

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
