  1. GCSE Mathematics Targeting Grade C Number Unit 1 Decimals

  2. If not you need • Can you… • Add and subtract decimals • Multiply decimals • Divide decimals • Try a test TOP: Review place value of decimals Practice 1: Add and subtract decimals Practice 2: Multiplying decimals Practice 3: Dividing decimals TAIL

  3. Top Write the value of the underlined digits in the following numbers. • 24.5 • 364.36 • 671.846 • 5737.36 • 8467.47234 • 473.5483 Lesson

  4. Practice 1: Add and subtract the following (remember to make sure the decimal points are in line, especially with the whole numbers). • 4.96 + 6.3 (2) 6.92 – 3.48 (3) 12.6 + 8.41 (4) 126.5 – 12.62 (5) 100.4 – 83.6 (6) 147.62 + 25.13 – 19.2 (7) 1596.5 + 154.258 (8) 357.25 – 159.29 (9) 657.65 + 165 – 65.28 (10) 125 – 36.52 + 12.147 Lesson

  5. Ignore the decimal points and multiply the numbers as normal (using long multiplication where necessary), then put the decimal point back at the end. REMEMBER there must be the same number of decimal places in the final answer as there was in the whole question!) Practice 2: Multiply the following decimals: • 25.4  0.6 • 1.26  1.3 • 0.65  1.5 • 36.4  5.8 • 12.6  13 • 6.4  9 • 53.4  2.1 • 23.4  0.12 Lesson

  6. Divide as normal then put the decimal point above the one in the question Practice 3: Find the answers to the following division problems: • 65.4  2 (2) 63.9  3 (3) 126.34  5 (4) 1.76  10 (5) 12.4  8 (6) 458.64  4 (7) 21.54  6 (8) 21.81  7 (9) 124.6  2 (10) 159.64  4 Lesson
