1) Divide the numerator by the denominator

Example- make 7/10 into 7÷10

2) Get your answer!

Example- The answer would be .7

Steps:

Skill 4:Changing a Fraction to a Repeating Decimal

Steps:

Skill 5: How to add Fractions with Same Denominators

Skill 7: How to Add Mixed Numbers

Steps:

1) Multiply the denominator by the mixed number

Example- 5 6/7 7×5=35

2) Add that number by the numerator

Example- 35+6= 41

3) Make that the numerator and make the origninal denominator your denominator

Example- 41/7

4) Repeat steps for other mixed number

5)Find LCD

Example- 41/7 8/3 LCD= 21

6) Add

Skill 2: Changing a Decimal into a Fraction

Skill 6: Adding Fractions with Unlike Denominators

Steps:

1) Find the Least Common Denominators (LCD) or the lowest multiple the denominators have in common

Example- 1/6 + 3/8 LCD= 24

2) Find what each denominator was multiplied by to get to the LCD and multiply the numerator by the same number the denominator was multiplied by

Example- 1/6= 4/24 3/8= 9/24

3) complete the same steps as Skill 5

Steps:

Steps:

1) Move the decimal two spots to the right. Is it a whole number? If it is, then make that the numerator and make the denominator 100. If it isn't a whole number, make it one, make that the numerator, and make 1000 the denominator

Example- .12 change to 12/100

2) Reduce!

Example- 12/100 reduced to 3/25

1) Make x= the repeating decimal

Examples( .7) x=(.7)

2) Write an equation

Examples- 10x= 7.(7)

3) Subtract the repeating decimal from both sides

Examples- 10x- x = 9x 7.(7)- .7

9x= 7

x= 7/9

1) Divide the numerator by the denominator

Example- 2/3 to 2÷3

2) Note- this only works for

some

fractions

Example 2÷3 = .66(6)

Steps:

1) Add the two numerators, but keep the denominators the same

Examples- 4/7 + 2/7 = 6/7

Skill 8: How to Subtract Fractions with same Denominators

Steps:

1) Subtract the numerators left to right, but keep the denominators

Example- 4/7 - 1/7 = 3/7

Skill 9: How to Subtract Fractions with Unlike Denominators

Steps:

1) Find LCD

Example- 4/7 1/3 LCD: 21

2)Multiply the numerators by the same number that the denominators were multiplied by to get to the LCD

Example- 4/7 7×3= 21 4×3= 12 12/21 1/3 3×7= 21 1×7= 7 7/21

3) Repeat steps for Skill 8

Skill 10: How to Add/Subtract Fractions that Contain Variables in the Denominator

Steps:

1) Find the LCD

Example- 3/x + 5/y LCD= xy

2) Cross multiply the variables and numbers

Example- 3y/xy + 5x/xy

3)Make into one fraction

Example- 3y + 5x/xy

Skill 11: How to Add/Subtract Fractions with Variables in the Numerator

Steps:

1) Find LCD

Example- 4y/a - 3x/b LCD= ab

2) Cross multiply the numbers and variables

Example- 4by/ab - 3xa/ab

3) Combine into one fraction

Example- 4by - 3xa/ab
