Step-by-step explanation:

Ms.Smiths has 28 sixth graders and 35 seventh graders. if she wants to break the two grades in to identically sized groups without any students left over, how many students should be in a group?

The key to solving this math problem is to add both the Sixth and Seventh graders, the divide them by three. You'll see that they divide equally into 3 groups of 21.

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.
