### Minioffice basic fractions_color

1. 1. Name ________________________ Fractions are numbers that tell how many parts of a whole. If you cut a pizza into 6 equal slices, you can use fractions to tell what part of the pizza you have. 1 2 3 6 6 6 4 5 6 6 6 6© 2008 abcteach.com
2. 2. NUMERATOR 3 tells how many parts we have 4 DENOMINATOR tells how many parts the whole is divided intoProper Fraction 3a part of 1 wholenumerator < denominator 4Improper Fractionone or more wholes, 12and part of anotherwhole 5numerator > denominatorMixed Numberthe same as an 2improper fraction, butwritten as a whole 2 5number and a properfraction© 2008 abcteach.com
3. 3. You can slice a pizza different ways, but if all the pieces are there it is still one whole pizza. If the numerator and denominator are the same, the fraction equals 1. 2 3 4 1 2 3 4 5 6 7 8 5 6 7 8 One pie has been cut into 8 equal pieces. The other has 8 2 been cut into 2 equal pieces. = 8 2 You can see that 4 pieces of one pie is the same amount of pie as 1 piece of the other pie. They are equal. 4 1 = 8 2© 2008 abcteach.com
4. 4. To add fractions, both fractions must have the samedenominator. That means that in both fractions the wholemust be divided into the same number of pieces. Then,just add the numerators. 2 + 3 = 5 8 8 8Just like when adding fractions, both fractions must havethe same denominator to subtract them. Then, subtractthe numerators. 5 - 4 = 1 6 6 6© 2008 abcteach.com
5. 5. These are easy to spot because the top number isbigger than the bottom number. Here’s why: 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2How many halves are colored?The answer is 7. 7So there are seven halves, or 2Improper fractions can also be written as mixed numbers. 1 1 2 2 1 whole 1 whole 1 wholeHow many whole blocks are colored?The answer is 3. 1So there are three wholes and one half, or 3 2© 2008 abcteach.com
