Review of Fractions
- Fractions were invented to express
numbers that are between whole numbers.
- Fractions can show measures between
whole numbers on rulers and scales.
- Fractions can name parts of a whole object
(for example, part of the eggs in a carton)
- Most fractions are fractions of something.
That something is referred to as the whole,
the ONE, or with measurements as the unit.
Review of Fractions continued
- Fractions can be written vertically or
horizontally.
- The number below(or to the right of) the
fraction bar is called the denominator.
- The denominator names the number of equal
parts into which the whole is divided.
- The number above(or to the left of) the fraction
bar is called the numerator.
- The numerator names the number of parts
under consideration.
Ex.
3/4. 3 is the numerator. 4 is the denominator.
A fraction may represent division. For
example, 3/4 is another way of saying 3
divided by 4.
Fractions can express probability. For
example, the chance that a die will land with
3 up is 1 out of 6, or 1/6
Fractions are used to compare 2 quantities as
ratios; 1 out of 2 students in the class is a
boy, so 1/2 of the class are boys.

Mixed Numbers and Improper Fractions
- Fractions that are equal to or greater than
1 are often called improper fractions.
- Improper fractions are an acceptable and
sometimes preferable form.
For example;
23/7 = 17/7
104/5 = 54/5
41/2 = 9/2
Mixed Numbers and Improper Fractions
- 41/2 is read as 4 and 1 half. It is called a
mixed number.
- It represents 4 + 1/2
- Mixed numbers are understood to be
addition expressions, but when they are
written, the addition symbol is not written.
For example,
26/6 = 38/6
