Identifying Fractions

Page 1

• Represent parts or pieces of a whole.
• Shows the operation of division.

Numerator 5

Denominator 8

*Draw a picture to represent this fraction.

Equivalent Fractions
• Fractions that show the same amount with a different amount of pieces. (equal)
• A fraction you get when you multiply or divide the numerator and denominator by the same number.

8 = 4 5 = 20 7x 3 = 32 ÷ 8 =

24 12 9 36 15x 3 72 ÷ 8

Simplest Form
• Showing the same amount by using the least number of pieces.
• Taking a fraction and dividing the numerator and the denominator by the same number (common factor) until you can’t divide anymore. Try finding the GCF to divide by!

12 ÷ =

64 ÷

*Draw a picture in your foldable book.

Comparing Fractions
• When the denominators are the same, just compare the numerators.
• When the numerators are the same, compare the denominators-the larger the denominator, the smaller the fractional pieces.
• When the numerators and the denominators are different, find a common denominator by creating equivalent fractions.

Ordering Fractions
• If the denominators are all the same, just compare the numerators and put them in order (least greatest).
• If the numerators are the same, compare the denominators and then put them in order. (just like <, >, or =)
• If necessary, make them all equivalent fractions and then put the original fractions in order.
• Add or subtract only the numerators in the fractions because you can’t change how many pieces they were originally divided into.

2 + 5 = 36 - 18 =

Identifying Mixed Numbers
• Represented by a whole number and a fraction together.
• When there is more than a fraction shown or a whole.
• In a division problem, the quotient represents the whole number, the remainder represents the numerator, and the divisor represents the denominator.

= 1 ¾

• Add or subtract the fractions first, regroup into the whole number column, if necessary.
• Then add or subtract the whole numbers.

Improper Fractions
• When the numerator is larger than the denominator.
• Shows the a mixed number too!

Converting Mixed Numbers & Improper Fractions
• Changing a mixed number improper fraction. Magic “C” +

1 x 4 =4 4 + 3 = 7 7

*Always put the answer over the same denominator!

Converting Mixed Numbers & Improper Fractions
• Changing a improper fraction mixed number .

7 means 7 ÷ 4 = 1 R 3 1 ¾

• The whole number in the quotient becomes the “whole” part of the mixed number. The remainder becomes the numerator and the denominator stays the same (divisor becomes the denominator).
