STUDENTS ARE GIVEN A HANOUT FOR THIS WITH KEY WORDS, EXAMPLES, AND THE SOLVE CHART
addition The act or process of combining numerical values, so as to find their sum
sum An amount obtained as a result of adding numbers
subtraction The arithmetic operation of finding the difference between two quantities or numbers
difference An amount obtained as a result of subtracting numbers
multiplication An arithmetic operation that is equivalent to repeated addition; the inverse of division; the product of two numbers is computed; "the multiplication of four by three gives twelve"; "four times three equals twelve".
reciprocal Any two numbers whose product is 1.
Example: ½ and 2 are reciprocals because ½ X 2 = 1
product An amount obtained as a result of multiplying numbers
division The operation of determining how many times one quantity is contained in another; the inverse of multiplication.
quotient An amount obtained as a result of dividing numbers
numerator The expression written above the line in a fraction
denominator The expression written below the line in a fraction that indicates the number of parts into which one whole is divided.
improper fraction A fraction in which the numerator is larger than or equal to the denominator. The value of an improper fraction is greater than or equal to one.
mixed number A numerical value that combines a whole number and a fraction
simplest form A fraction is in simplest form when the greatest common factor of the numerator and denominator is 1.
simplify To reduce the numerator and the denominator in a fraction to the smallest form possible. To divide the numerator and denominator by the GCF is simplifying a fraction.
LCD The least common multiple of the denominators of two or more fractions. Example: 6 is the least common denominator of 2/3 and 1/6.
estimate To make an approximate or rough calculation, often based on rounding

Improper Fractions
the numerator part greater or equal to the denominator
ex-17/2 or 5/5
How to make an improper to a mixed:
DIVIDE the numerator by the denominator
Practice / / /4
Mixed Fractions
a whole number plus a fraction
ex-2 ½ or 1 ¼  .      
How to make a mixed an improper:
Multiply the whole number by the denominator, then add on the numerator. This is your new numerator. The denominator stays the same!
Practice ¼ ¾ /5
Remember to simplify whenever possible (GCF)!

4. Or make equivalents and regroup 3 ½ = 2 /4 + 2 ¾ = 3 /4 5 5/4 = 6 ¼
Adding Fractions pg 32
Find the least common denominator (LCM) and make equivalent fractions
2/3 = 8 /12
/4 = 9 /12
17/12 = /12
With mixed numbers you can change your mixed to improper then equivalents
3 ½ = 7/2 = 14 /4
+ 2 ¾ = 11/4 = 11/4
25/4= 6 ¼
Or make equivalents and regroup
3 ½ = 2 /4
+ 2 ¾ = 3 /4
/4 = 6 ¼
Pg 31
Practice
4/5 + ¾
3 ¾ + 2 ½
7/12 + 5/6

5. Subtracting Fractions pg 34
Find the least common denominator (LCM) and make equivalent fractions
2/3 = 8 /12
/4 = 3 /12
5/12
With mixed numbers you can change your mixed to improper then equivalents
4 ½ = 9/2 = 18 /4
- 2 ¾ = 11/4 = 11/4
7/4 = 1 ¾
Or make equivalents and regroup
4 ½ = /4 (borrow) 3 2/4 + 4/4= 3 6/4
2 ¾ = 2 ¾ ¾
1 ¾
Pg 33 Practice
5/8 – 5/12=
2 7/8- 5/6=
10 – 4 ¾ =
