Question

Monica and Sasheer want to divide 42÷6. Monica knows that 6+36=42, so she says that 42÷6= 36. Sasheer knows that 6x7=42, so she says that 42÷6=7. Whose reasoning is corect explain?

Answer 1

Sasheer

Since I know 42 divided by 6 is 7, Monica is right. But, to double check, you can use the inverse of division (multiplication, like what Sasheer said).

Answer 2

There are inverse operations that need to be acknowledged. The inverse operation for division is multiplication and vice versa while the inverse operation for subtraction is addition and vice versa. Therefore, Sasheer's reasoning is correct.
