Write integers as powers of 10 6c 0.001 = 10-3 0.01 = 10-2 0.1 = 10-1 1 = 100 10 = 101 100 = 102 1000 = 103 10000 = 104 100000 = 105 10000000 = 106 01 November 2019

Multiply by 0.1 and 0.01 6c Multiplying by 0.1 is the same as multiply by 1 10 which is the same as ÷ 10 70 x 0.1 = 7 23 x 0.1 = 2.3 0.7 x 0.1 = 0.007 0.0123 x 0.01 = 0.00123 Multiplying by 0.01 is the same as multiply by 1 100 which is the same as ÷ 100 300 x 0.01 = 3 4567 x 0.01 = 45.67 0.9 x 0.01 = 0.009 0.023 x 0.01 = 0.00023 01 November 2019
