Ignore –just for now- the decimal point. Also ignore –for now- any zeroes at the start of the decimalnumber.Now multiply the two numbers in the same way you would multiply any two whole numbers.2. Count the number of digits following the decimal point in the original decimal number.3. Insert a decimal point in the answer you obtained in step 1, ensuring the number of digits that follow itequals the number of digits obtained in step 2.4. Simplify if necessary, as in examples 2-4.Example 1 Example 2 Example 3 Example 4Find 0.6 of 2 Find 0.6 of 20 Find 0.25 of 80 Find 0.25 of 8006 x 2 = 12 6 x 20 = 120 25 x 80 = 2 000 25 x 800 = 20 0001.2 12.0 20.00 200.012 20 200Now try these:1 Find 0.3 of 6 2 Find 0.4 of 12 3 Find 0.9 of 20 4 Find 0.1 of 535 Find 0.25 of 4 6 Find 0.25 of 80 7 Find 0.75 of 4 8 Find 0.75 of 409 What is 0.65 of 12? 10 What is 0.35 of 4? 11 What is 0.28 of 15?12 How much is 0.9 of 9? 13 How much is 0.9 of 900?14 How much is 0.55 of 40? 15 How much is 0.82 of 200?16 Find 0.99 of 30 17 Find 0.99 of 3 18 Find 0.99 of 3 00019 Find 0.11 of 11 20 Find 0.12 of 9 21 Find 0.09 of 20022 What is 0.999 of 20? 23 What is 0.015 of 600? 24 What is 0.229 of 30?25 How much is 0.186 of 1 000?No. Correct % Score Signature or Comment© Intelligent Australia Productions 25
