  • What are equivalent fractions?
  • Can you give me some examples?

Converting Fractions to Decimals
  • To convert a Fraction to a Decimal manually,
    follow these steps
  • Step 1 Find a number you can multiply by the
    bottom of the fraction to make it 10, or 100, or
    1000, or any 1 followed by 0s.
  • Step 2 Multiply both top and bottom by that
    number.
  • Step 3. Then write down just the top number,
    putting the decimal place in the correct spot
    (one space from the right for every zero in the
    bottom number)

Method 1 Converting with Proportions
  • Example 1 Express 3/4 as a Decimal
  • Step 1 We can multiply 4 by 25 to become 100
  • Step 2 Multiply top and bottom by 25
  • 3 75
  • 4 100

5
Example 1 continued.
  • Step 3 Write down 75 with the decimal place 2
    spaces from the right (because 100 has 2 zeros)
  • Answer 0.75

6
Practice Question
  • Express ¼ as a decimal.

7
Method 2 Convert by Dividing
  • Example 1 to write 5/8 as a decimal, we need
    to calculate 5 8 0.625
  • 8 v 5.000
  • So 0.625 as a decimal.

8
Practice Question
  • Write 4/5 as a decimal using division.
