Fractions+and+decimals

1. **Converting a decimal to a fraction**
 * When converting a decimal to a fraction what do we put as the denominator before we cancel?
 * Convert 0.60 into a fraction. What is it?
 * What about 0.250?
 * And, 1.7?

2. **Quiz time**
 * First group to tell me what the Review says on page 122

3. **Commit to memory these facts**
 * 1/2 = 0.5
 * 3/4 = 0.75
 * 1/5 = 0.2
 * 1/4 = 0.25
 * 1/8 = 0.125
 * 1/10 = 0.1

4.**To convert a fraction to a decimal we can...** a. Use known facts e.g.
 * To convert 5/8 to a decimal we can use the known facts above to help us.
 * 1/8 = 0.125................So, 5/8 = 0.125 x 5..........Which, = 0.625
 * Have a go at Questions 1d, f, j & n

b. Make an equivalent fraction with denominator 10 or 100 then divide e.g.
 * We could 9/25 = 36/100 = 0.36
 * 12/30 = 4/10 = 0.4
 * Have a go at questions 2a, d, l & p

c.Divide the numerator by the denominator e.g. __-4.8__ 0.20 -__0.16__ 0.040 -__0.040__ 0.0 //Answer 0.625//
 * we could 5/8 = 8)5.0
 * Have a go at Questions 4 a & h

5. **Terminating or recurring decimals**
 * 0.625 and 6.2 are terminating decimals because they end
 * Recurring digits have one or more digits that repeat e.g. 1/3 = 0.3333... here we would put a dot above the 3
 * With two digits we would put a dot above both e.g. 3/11 = 0.272727... here we put a dot above 2 & 7
 * When the repeating pattern is longer than two we usually round the decimal e.g. 3/7 would be 0.428571428571, but rounded it would 0.43
 * Have a go at Qestion 8 a & i
