Division with 2-digit divisors

Front

What is division?

Back

Division is the process of determining how many times one number (the divisor) is contained within another number (the dividend).

Front

What is a 2-digit divisor?

Back

A 2-digit divisor is a number that has two digits, ranging from 10 to 99, used to divide another number.

Front

How do you solve a division problem with a 2-digit divisor?

Back

To solve a division problem with a 2-digit divisor, you can use long division or estimation to find how many times the divisor fits into the dividend.

Front

What is the quotient in a division problem?

Back

The quotient is the result of dividing one number by another.

Front

What is a remainder in division?

Back

A remainder is the amount left over after division when the dividend is not evenly divisible by the divisor.

Front

How can you check your division answer?

Back

You can check your division answer by multiplying the quotient by the divisor and adding the remainder (if any) to see if it equals the dividend.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations; if you multiply the quotient by the divisor, you should get the dividend.

Front

How do you interpret a word problem involving division?

Back

To interpret a word problem involving division, identify the total amount (dividend), the number of groups (divisor), and what you need to find (quotient or remainder).

Front

What is the importance of estimating in division?

Back

Estimating in division helps to quickly determine a reasonable range for the quotient, making it easier to check the accuracy of the final answer.

Front

What is the standard algorithm for long division?

Back

The standard algorithm for long division involves dividing, multiplying, subtracting, and bringing down the next digit in a systematic way until all digits have been processed.
