1 Multiplying by 10, 100 or 1000 x 100 = x 100 = x 100 = x 100 = x 100 = x 100 = C. ÷x 0 + On ² - Ans = √ (-) Whole Number 1dp 2dp Show Answer Multiply by100

2 Multiplying a Decimal by 10,100 or x 1000 Copy Down Whole Number Add one arrow for each 0. Add any other digits Place Point = C. ÷x 0 + On ² - Ans = √ (-) New Example 24.25

3 Multiplying by 10, 100 or x x x x x x C. ÷x 0 + On ² - Ans = √ (-) = = = = = = Next Six

4 Multiplying by a Multiple of 10 Example 9.3 x C. ÷x 0 + On ² - Ans = √ (-) Copy down the decimal number Split the 2 nd value into a number times 10 or 100 or 1000 or …. Multiply by the 10, 100, 1000 Multiply this number by single digit Next

5 Multiplying by multiple of C. ÷x 0 + On ² - Ans = √ (-) x 60 == = 12.1 x 90 == = x 40 == = x 50 == = 4.9 x 300 == = Next Five Show Show Answers

6 x6 C. ÷ x 54 + On ² - Ans = √ (-) C. ÷x 0 + On ² - Ans = √ (-)
