11 . NUMERATOR AND DENOMINATOR eg / FRACTIONS : REVISION SHEET is the numerator; (how many parts of the whole that have been used) is the denominator (how many parts the whole is divided into) 2. SIMPLIFY getting the fraction to the smallest possible number For example: /30 I look at and say it consists of ( x ; x 3); I choose the biggest number that will also go into 30. In this case,, and 3 will go into 30. I choose because it is the biggest number. You can choose the other numbers, but then you have to simplify more times. In Maths we always look at the quickest way to do something. Do the following sums in your exercise book : simplify Exercise a) 4/22 b) 2/3 c) 9/2 d) 0/30 e) /4 f) 7/2 g) 22/33 h) 0/00 i) 36/4 j) 2/6 Exercise 2 a) 6/32 b) 2/6 c) 66/77 d) 36/2 e) 6/42 f) 9/36 g) /9 h) 3/9 i) 20/2 j) 2/

12 3. OF For example: find ½ of 6 Say to yourself: 6 divided by 2 (Answer is ) Then you say: x = (which is your answer) For example: find ¾ of 24 Say to yourself: 24 divided by 4 (Answer is 6) Then you say: 6 x 3 = 24 (which is your answer) Exercise a) / of 24 b) /9 of c) /3 of d) / of e) /2 of 44 f) 3/ of 2 g) 4/9 of 36 h) 2/3 of i) 6/ of 4 j) 3/ of TYPES OF FRACTIONS Proper Fraction 3/ Improper Fraction 6/4 Mixed Fraction: 2 ½ Equal Fraction ½ = ½ Equivalent fraction ALL EXERCISES TO BE DONE IN YOUR EXERCISE BOOK Exercise : Change Improper fractions into Mixed Fractions 4/6 is equivalent to 2/3 a) 7/2 b) 9/4 c) 0/3 d) 3/2 e) /4 e) / f) /4 g) /2 2

13 Exercise 2: Change Mixed Fractions into Improper Fractions a) 2 ½ b) 3 4/ c) ¾ d) 3 2/3 e) 2 ¾ e) 3 /6 f) 3 /6 g) /3 Exercise 3: Fill in equivalent fractions for: a) 2/3 b) c) 3/ d) /2 ) ADDING AND SUBTRACTION OF FRACTIONS Exercise 4: Plus and minus with the same denominator a) ¼ + /4 b) 4/ + 3/ c) 4/6 2/6 d) / 3/ Exercise : Plus and minus with different denominators a) ¼ + 3/ b) 3/ + 6/0 c) 2/3 /6 d) 3/4 2/2 3
