Question

a teacher has a bag of 100 unit cubes. She gives an equal number of cubes to each of the 7 groups in her class. She gives each group as many cubes as she can. How many unit cubes are left over?

Answer 1

7 x 14 = 98, 100 - 98 = 2.

She gives 14 cubes to each group, and there are 2 cubes leftover.

Hope this helps!
