Working with fractions at l1

  1. 1. Adult Numeracy Level 1 Working With Fractions Dave Cross Suffolk New College
  2. 2. Fractions at Level 1 <ul><li>A fraction shows a number as mixture of whole numbers (integers) and parts of a whole (fractions) </li></ul>One and a Half = = = 1.5 Or Three Halfs One whole and one half 1- 2 1 3-2

  5. 5. Fractions at Level 1 <ul><li>To turn an improper fraction into a mixed fraction we need to find how many times we can get the denominator into the numerator, using division </li></ul>So here we divide 3 by 2 giving one and a half Thus 3/2 (improper) = 1 ½ (Mixed) 2 3
