Can you now represent the following numbers as decimal? Hundreds 100 Tens 10 Ones 1 Tenths 1 10 5 3 8 1 2 7 3 4 3 5 4 6

To convert place value table into decimal, find place value of each digit and sum up all values as shown below: 1 . 5 × 100 + 3 × 10 + 8 × 1 + 1 × 1 10 = 500 + 30 + 8 + 0 . 1 = 538 . 1 2 . 2 × 100 + 7 × 10 + 3 × 1 + 4 × 1 10 = 200 + 70 + 3 + 0 . 4 = 273 . 4 3 . 3 × 100 + 5 × 10 + 4 × 1 + 6 × 1 10 = 300 + 50 + 4 + 0 . 6 = 354 . 6 Here, we can represent as: Hundreds 100 Tens 10 Ones 1 Tenths 1 10 Decimals 5 3 8 1 538 . 1 2 7 3 4 273 . 4 3 5 4 6 354 . 6

Write 3 2 , 4 5 , 8 5 in decimal notation.

To write in decimal form, the denominator must be multiples of 10 . Multiplying numerator and denominator of 3 2 by 5 , 3 2 = 3 × 5 2 × 5 = 15 10 = 1.5 Multiplying numerator and denominator of 4 5 by 2 , 4 5 = 4 × 2 5 × 2 = 8 10 = 0.8 Multiplying numerator and denominator of 8 5 by 2 , 8 5 = 8 × 2 5 × 2 = 16 10 = 1.6 Hence, the required answers are 1 . 5 , 0 . 8 and 1 . 6 respectively.
