  2. 2. A Fraction Is...  A fraction is a number  ¼ , one fourth, that names a part of a means one out of whole number four  A numerator is the top number  The denominator is the total of the whole number
  3. 3. Conversions  To change a fraction into a decimal you...  You first have to divide the denominator into the numerator  You then, add a decimal point and zeros until you do not have a remainder  An example is, 8/10 and 0.8
  4. 4. Adding Fractions  To add fractions and  To add fractions and common denominators uncommon denominators you add the numerators you find the LCD with those numbers  Then you keep the denominator the same  Then you change the denominator  Finally you simplify  Lastly you add the  Then you get your numerators answer  You then have yoyur answer
  5. 5. Mixed Numbers  You first have to change  To divide you turn the it into an improper mixed number into a fraction improper fraction  You multipy the  After that you subtract denominator with the  Then you simplify if you whole number then you can take that number and add the numerator to get  Lastly, you turn it back into the improper fration a regular fraction by dividing the numerator by  You then add the the denomanator fractions and turn it into a regular fraction by dividing the numerator by the denomanator
  6. 6. Multipling and Dividing Fractions  First you line up the  First you line up the fractions fractions  Next you multiply the  Then you divide the numerators numerator  Then you get your  Next you leave the answer denomanator the same  Finally you get your answer
