Moving left in a number increases its place value
Moving left from the decimal point the place value of the digits is as follows: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions...
14
Multiple Choice
Which answer below correctly rounds 745,234,189 to the nearest thousand?
745,000,000
745,234,200
745,234,000

15
Moving right in a number decreases its place value.
Moving right from the decimal point the place value of the digit is as follows: tenths, hundredths, thousandths, ten thousandths, hundred thousandths, millionths
16
The number 54,278.931 can be separated into place value like this:
5: ten thousands
4: thousands
2: hundreds
7: tens
8: ones
9: tenths
3: hundredths 1: thousandths

The following roots are helpful to understand the metric system:
Deci=10th
Centi=100th
Milli=1000th
Deca=10
Hecto=100
Kilo=1000
Therefore 1 kilometer = 1000 meters = 100,000 centimeters
19
Multiple Choice

Perimeter is adding up all sides of an object, say for a rectangle, you would add up 2 widths and 2 lengths
22
Multiple Choice
The high school grounds are rectangular in shape with sides that are 160 yards wide by 630 yards long. Approximately how much fencing would the school need to buy in order to surround the perimeter of the grounds?
800 yards
1600 yards
100,800 yards
2000 yards
23
For height, you use multiplication. For example, if the height of a 7-story building if each story is 11.8 feet high, then the height of the building is about 84 feet.
For area, you use A =s2
24
In a fraction the top number is called the numerator and the bottom number is the denominator
6 Numerator
8 Denominator

When adding or subtracting fractions, the denominators must be the same
5/6 - 2/3 = 5/6 - 4/6 = 1/6
28
Multiple Choice
What is the sum of 1/4 and 3/8?
5/8
6/8
5/16
1/16
29
When multiplying fractions the numerators and denominators do not need to change
5/11 x 3/7 = 15/77
30
Fractions can be divided using multiplication principles
2/7 / 3/5 = 2/7 x 3/5 = 10/21
31
A fraction can be turned into a decimal by dividing the numerator by the denominator. This decimal can be represented as a % by moving the decimal two places to the right and adding a % sign
Example: 1/4 = .25 = 25%
32
Multiple Choice
The fraction 1/5 can be represented by which percentage?
25%
20%
40%
80%
33
Any % can be turned into a decimal by removing the % sign and moving the decimal two places to the left. Any % can be turned into a fraction by placing the value over 100.
Example: 9% = .09
9% = 9/100
34
Multiple Choice
What is 40% written as a fraction?
2/5
3/5
1/6
2/3

Multiple Choice
A recent poll of 20,000 residents showed that 60% of residents are in favor of building a new pavilion at the park. How many residents are not in favor of building the pavilion?
12,000
8,000
18,000
1,200

When multiplying numbers with decimals, the decimal point in the product must be moved to the left the total number of places in both of the original numbers.
39
Example:
.57
x.20
00
1140
.1140 or 0.114
40
When dividing numbers with decimals, the decimal point in the divisor should be moved to the right to create a whole number. The decimal point in the dividend must then be moved an equal number of places
41
Example:
8.2/9.84 = 1.2
