Blake solved the following division exercise : 136 divided by 3 = 44 R4. Explain how you know the answer is wrong just by lookin

son4ous [18]

The remainder (which is what Blake says is the remainder), can never be more than the number you are dividing by (the dividend), which in this problem is three.
