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

Converting Fractions to Decimals
• To convert a Fraction to a Decimal manually,
• 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)

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.

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