Write a division problem that will have a 2 digit quotient and another division problem that will have a 3 digit quotient. Explain how you choose the divisors and dividends.

Answers

Answer:

(240)/(4) =60

(1800)/(3) =600

Step-by-step explanation:

1.  The result should by a 2 digit number.

So, I fix a two digit number first, say 60.

Then, I multiplied it by some random integer, say 4 and got 240.

Now, 240 is my dividend and 4 is my divisor.

My division problem is:

(240)/(4) =60


2.  The result should be a 3 digit number.

So, I fix a three digit number first, say 600.

Then, I multiplied it by some random integer, say 3 and got 1800.

Now, 1800 is my dividend and 3 is my divisor.

My division problem is:

(1800)/(3) =600

1. 150 divided by 5= 30
2. 1,000 divided by 10= 100
