MULTIPLYING AND DIVIDING WITH NEGATIVES

Fractions
LEAST COMMON MULTIPLE
The LCM of a set of numbers is the smallest number that is a multiple of all the given numbers. For example,the LCM of 5 and 6 is 30, since 5 and 6 have no factors in common.GREATEST COMMON FACTOR
The GCF of a set of numbers is the largest number that can be evenly divided into each of the given numbers. For example,the GCF of 24 and 27 is 3, since both 24 and27 are divisible by 3, but they are not both divisible by any
numbers larger than 3.FRACTIONS
Fractions are another way to express division. The top num- ber of a fraction is called the numerator , and the bottom number is called the denominatorADDING AND SUBTRACTING FRACTIONS
Fractions must have the same denominator before they can be added or subtracted. , with . , with . If the fractions have different denominators, rewrite them as equivalent fractions with a common denominator. Then add or subtract the numerators, keeping the denominators the same.For example,
23+14=812+312=1112dZ0a

Rates,Ratios,Proportions,
and PercentsRATES AND RATIOS
A rateis a comparison of two quantities with different units. For example, a car that travels 110 miles in 2 hours is mov- ing at a rate of 110 miles/2 hours or 55 mph. A ratio is a comparison of two quantities with the same units. For example, a class with 23 students has a student-teacher ratio of 23:1 or .PROPORTIONS
A proportion is a statement in which two ratios or rates are equal. An exampleof a proportion is the following statement:30 dollars is to 5 hours as 60 dollars is to 10 hours.
This is written
A typical proportion problem will have one unknown quantity, such as We can solve this equation by cross multiplying as shown:So, it takes 60 minutes to walk 3 miles.
PERCENTS
A percent is the number of parts out of 100. To write a per- cent as a fraction, divide by 100 and drop the percent sign.For example,
To write a fraction as a percent, first check to see if the denominator is 100. If it is not, write the fraction as an equivalent fraction with 100 in the denominator. Then the numerator becomes the percent.For example,
To find a percent of a quantity, multiply the percent by the quantity.For example
, 30% of 5 is 30100
5=150
100=324
5=80100=80%57%=57
100x=60
20=320x=60

20 min=x miles60 min$30
5 hr=$6010 hr
231Fractions (continued)
Equivalent fractionsare found by multiplying the numerator and denominator of the fraction by the same number. In the previous example, and.MULTIPLYING AND DIVIDING FRACTIONS
When multiplying and dividing fractions, a common
denominator is not needed. To multiply, take the product of the numerators and the product of the denominators: To divide fractions, invert the second fraction and then multiply the numerators and denominators:Some examples:
REDUCING FRACTIONS
To reducea fraction, divide both the numerator and denom- inator by common factors. In the last example,MIXED NUMBERS
A mixed number has two parts: a whole number part and a fractional part. An example of a mixed number is . This really represents which can be written as Similarly, an improper fraction can be written as a mixed number.For example,
can be written as , since 20 divided by 3 equals 6 with a remainder of 2.6 2 3 20 3408+38=4385+3
