Dividing a Decimal by a Decimal

Dividing Whole Numbers 12 ÷ 2 = 120 ÷ 20 = 1200 ÷ 200 = ÷ 2000 = Multiply both 12 and 2 by 10 Multiply both 120 and 20 by 10 Multiply both 1200 and 200 by 10

Dividing Decimals 12 ÷ 2 = 1.2 ÷ 0.2 = 0.12 ÷ 0.02 = ÷ = Divide both 12 and 2 by 10 Divide both 1.2 and 0.2 by 10 Divide both 0.12 and 0.02 by 10

Dividing Decimals 12 ÷ 2 = ÷ 0.2 = We know how to divide this And we know this will give us the same answer So how do we get from this to this? How did we turn 0.2 We multiplied by 10 (in effect, moving the decimal one place to the right) To make it work, we also need to multiply 1.2 by 10 (in effect, moving the decimal one place to the right into 2?..

Dividing Decimals 12 ÷ 2 = ÷ 0.02 = We know how to divide this And we know this will give us the same answer So how do we get from this to this? How did we turn 0.02 We multiplied by 100 (in effect, moving the decimal two places to the right) To make it work, we also need to multiply 0.12 by 100 (in effect, moving the decimal two places to the right into 2?..

Dividing Decimals 12 ÷ 2 = ÷ = We know how to divide this And we know this will give us the same answer So how do we get from this to this? How did we turn We multiplied by 1000 (in effect, moving the decimal three places to the right) To make it work, we also need to multiply 0.12 by 1000 (in effect, moving the decimal three places to the right into 2?..
