Multiplying fractions


TOP
Ex  1 -             1/2  x 2/5  =   2/10=1/5

Ex 2-               2/3    x 9/16  =  18/48    =  3/8

Ex 3  -        1    2/5  x  2    2/7  =     7/5   x   16/7  =    112/35       3  7/35  reduces   3    1/5



BOTTOM
*Make sure you have each fraction written in a/b form.

*Multiply straight across (or simplify before you multiply)

Vocabulary Words

1.  prime- A Prime Number can be divided evenly only by 1, or itself. And it must be a whole number greater than 1.  Examples of prime numbers include 2,3,5,7,11.

2.  composite A whole number that can be divided evenly by numbers other than 1 or itself. Example: 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is a composite 

3.  distributive property    The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, that 2(3 + 4) = 2×3 + 2×4.

4.  product-a product is the result of multiplying

5.  multiples-  The result of multiplying a number by an integer (not a fraction).

6. factors-Factors are numbers you can multiply together to get another number: Example: 2 and 3 are factors of 6, because 2 × 3 = 6. 

7. greatest common factor -The largest common factor of two or more given numbers.

8. least common multiple-The smallest number, other than zero, that is a multiple of two or more given numbers.

9.  inequality- A mathematical sentence that shows the relationship between quantities that are not equal.

10.  Integer- a member of the set of whole numbers and their opposites.

11.  positive numbers- A number greater than zero

12. negative numbers- a number less than zero

13.  absolute value- The distance of a number from zero on a number line: shown by |   | lines.

14. opposites- two numbers that are an equal distance from zero on a number line.
