Question

Two fifth graders solved 400,000 divided by 800. Carter said the answer is 500, while Kim said the answer is 5,000.

Answer 1

Answer:

a) Carter

b)500

Step-by-step explanation:

a)

Correct answer:

 800)400,000(500

         400,000

               0

When 400,000 divided by 800 then we will get 500.

So Carter answer is correct and Kim answer is wrong.

b)

 8,000)4,000,000(500

            4,000,000

                 0

Here quotient is 500 and remainder is 0.

So the  quotient is 500.

         

Answer 2

Answer:

a. Carter is correct. (See explanation).

b. The quotient is $500$ (The quotient of $400,000$ divided by $800$ and the quotient of  is $4,000,000$ divided by $8,000$ are equal).

Step-by-step explanation:

a. Carter is correct.

The dividend $400,000$  and the divisor $800$ have two zeros in common, so we can eliminate those zeros. Then:

$4,000\div8$

We know that the quotient obtained by dividing $40$ and $8$ is $5$:

$40\div8=5$

 Since$4,000$ has two more zeros than $40$, we must place two zeros in the quotient. Then:

$=500$

b. The dividend $4,000,000$  and the divisor $8,000$ have three zeros in common, so we can eliminate those zeros. Then:

$4,000\div8$

Notice that this is the same as the exercise "a". So the quotient will be the same.

Let's check. We know that:

$40\div8=5$

 Since$4,000$ has two more zeros than $40$, we must place two zeros in the quotient. This is:

$=500$
