Which of the following can be used to find 56 divided by 4?
A) (4x7) + (4x8)
B) (4x50) + (4x6)
C) (2x28) + (2x2)
D) (4x10) + (4x4)
Possibly d). If you can multiply any number by four and the resulting product is less then the 56 then you can subtract that product from 56 and be left with a smaller number that you can perhaps divide by 4 in your head. This 'might' be the idea behind the exercise.
