Ответ:
a) Carter
b)500
Step-by-step explanation:
a)
Correct
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.
Ответ:
a. Carter is correct. (See explanation).
b. The quotient is (The quotient of divided by and the quotient of is divided by are equal).
Step-by-step explanation:
a. Carter is correct.
The dividend and the divisor have two zeros in common, so we can eliminate those zeros. Then:
We know that the quotient obtained by dividing and is :
Since has two more zeros than , we must place two zeros in the quotient. Then:
b. The dividend and the divisor have three zeros in common, so we can eliminate those zeros. Then:
Notice that this is the same as the exercise "a". So the quotient will be the same.
Let's check. We know that:
Since has two more zeros than , we must place two zeros in the quotient. This is:
Ответ:
Answer is 6600.
