Lesson 11: Terminating and Repeating Decimals
Terminating:
A decimal quotient that terminates or stops because the repeating block of digits consists only of zeros.
Repeating:
A decimal quotient that contains a repeated block of digits.
Lesson 10: Fractions, Mixed Numbers and Decimals
To find the least to greatest among these three numbers 0.65, 0.85, 15/20 make them all into fraction in either of the 3 place values 10, 100, 1000 so 65 and 85 are closer to 100 than 10 and 1000,and then you can make 15/20 a higher fraction, so you can times 15 and 20 with 5 so it would be 75/100
LESSON 9: Compare and Order Fractions
To compare and order fractions:
1.First look at the denominators (the bottom numbers).
2.Find a new number that both denominators go into
3.Now you have found a new denominator that is divisible by both numbers, you need to change the numerators (the top numbers)

LESSON 8: Simplest Form
A fraction whose numerator and denominator have divided into the smallest fraction it can be from its product.
Example:
LESSON 7: Equivalent Fractions
Equivalent Fractions are fractions that show different number with the same value.
Example:
LESSON 6: LCM(Greatest Common Multiple):
The least common multiple is the smallest number that divides into the 2 or more numbers.
Example:
LESSON 5: GCF (Greatest Common Factor):
The greatest common factor is the easiest way to find the biggest factor of one number that is given. The greatest common factor is also known as the greatest common divisor.
Example:
LESSON 4: Divisibility Rules
Here are the divisibility rules from 2-10 and some examples too.
The number is 231:
2-the number must be even=no
3- the sum of all the numbers must be a multiple of 3
example: 231= 2+3+1=6 6÷3=2=yes
4-the last 2 digits must form a number that is a multiple of 4
231=31=no
5-the number must end with 5 or 0=no
6-the number must be divisible by 2 and 3
8-the last 3 digits must form a number that is a multiple of 8
9-the sum of the digits must be a multiple of 9
10-the last digit must be 0
7-Double the number then cross it out and the answer of the doubled last number and subtract from the rest.
Step 1: 231 take out the 1 = 23 Step 2:double the last digit you took out which is 1 = 1+1=2 Step 3:then subtract what is left with 2 = 23 -2 = 21
=yes
3- the sum of all the numbers must be a multiple of 3
example: 231= 2+3+1=6 6÷3=2=yes
4-the last 2 digits must form a number that is a multiple of 4
231=31=no
5-the number must end with 5 or 0=no
6-the number must be divisible by 2 and 3
8-the last 3 digits must form a number that is a multiple of 8
9-the sum of the digits must be a multiple of 9
10-the last digit must be 0
7-Double the number then cross it out and the answer of the doubled last number and subtract from the rest.
Step 1: 231 take out the 1 = 23 Step 2:double the last digit you took out which is 1 = 1+1=2 Step 3:then subtract what is left with 2 = 23 -2 = 21
=yes
Example with the rules:
LESSON 3: Prime Factorization
Prime factorization is factoring a number into its prime factors only.
Example:
LESSON 2: Exponents
The number in a power that tells how many times the factor is repeated in a product.
Example:
LESSON 1: Factors and Prime Numbers
A factor is one or more numbers that are multiplied by another number to create the product and a prime number is a number that has only two factors, 1 and itself and numbers that don't have only two factors are called composite numbers.
Example: But this example is not a prime number
Imagine if it was 13 then it will have only two factors 1 and 13.
