Dividing Decimals Find the quotient of 12 ÷ 4 Set it up quotient Dividend (in the box) Divisor (out of the box) Find the quotient of 156 ÷

Dividing a whole number by a whole number We are able to divide these numbers because the divisors are whole numbers! divisor Sometimes, we have to do a little more…………………..

Dividing a whole number by a DECIMAL What if the divisor is NOT a whole number?? Example: 156 ÷ 1.2 Set it up The divisor is NOT a whole number! We have to change the divisor to a whole number by moving the decimal to the right (which is the same thing as multiplying by a power of 10) (x 10, x 100, x 1000, etc.)

Dividing a whole number by a DECIMAL Example: 156 ÷ 1.2 We have to change the divisor to a whole number by moving the decimal to the right. We had to move the decimal 1 place to the right, to make the divisor a whole number We have to move the decimal the same number of places in the dividend also! (1 place) 0

Dividing a whole number by a DECIMAL Bring the decimal straight up to the quotient Now, you are ready to divide! Now, CHECK IT by multiplying! 130 X

Dividing a DECIMAL by a DECIMAL Bring the decimal straight up to the quotient Now, you are ready to divide! Now, CHECK IT by multiplying! 1.3 X Find the quotient 1.56 ÷ 1.2

Dividing a DECIMAL by a DECIMAL Bring the decimal straight up to the quotient Now, you are ready to divide! Now, CHECK IT by multiplying! 130 X Find the quotient 15.6 ÷

Dividing Decimals Change the divisor to a whole number by moving the decimal to the right. Move the decimal the same number of places in the dividend If you don’t have to move the decimal in the divisor, you don’t move it in the dividend either! Bring the decimal straight up to the quotient Divide Check your solution by multiplying!
