Divide 2-digit number by 1-digit number with zero remainder
I have 30 marbles and I want to place then in 6 jars equally. How many marbles can be placed in each jar?
Dividing 30 by 6, we get 5.
Total number of marbles = 30
Numbers of jars = 6
Number of marbles in one jar = 30 / 6 = 5
Thus, 5 marbles can be placed in each jar.
Key Fact: When 2-digit number is divided by 1-digit number, we divide the number at tens place first and then the number at ones place. Division means to distribute the things equally.
Apply mental strategies to divide 1-digit number by 1-digit number.
Consider the division of the following numbers.
- 6 / 2 = 3
- 9 / 3 = 3
- 8 / 2 = 2
- 8 / 4 = 2
