Dividing multiples of 10
Topic Notes
In this lesson, we will learn:
- Patterns in dividing by 10, 100 and 1000
- Patterns in dividing by multiples of 10
Notes:
A multiple of 10 is any number that has 10 as a factor (Shortcut: a multiple of 10 is any number that ends in zero)
- To divide a whole number by 10, 100, 1000 (or their multiples)
- Divide the nonzero digits
- Count the number of zeroes in the divisor
- Erase the same amount of zeroes from the dividend to get the quotient
- Ex. 2100 ÷ 70 = 30 (One zero in 10, get rid of one zero from the 2100 so there is one zero in the quotient)
Ex. 800 ÷ 10 = 80 (One zero in 10, get rid of one zero from the 800)
