Question

can be used to check 10÷5=___
.

Is Lee correct? Explain how you know if he is right or wrong.

Answer 1

Yes, Lee is correct. The multiplication fact 5×5=25 can be used to check the division problem 10÷5=2. When we divide 10 by 5, we are essentially trying to find out how many times 5 can be subtracted from 10. The answer is 2. So, if we multiply 5 by 2, we get 10, which verifies that the division problem is correct.
