Example: 5/12 x 1/10=

5/12 multiply 2= 10/24

10/24 + 3/24= 7/24

• Addition fractions with unlike denominators, find the LCD by listing the multiple of each denominator.
• If the denominator (bottom number is changed, the numerator must also be changed by the same number.

139

Example: 1/5 x 7/10=

1/5 x 2 top and bottom = 2/10

7/10 x 2= 14/20

_2_+ _7_= _9_
10 10 10

• Subtracting fractions with unlike denominators, find the LCD by listing multiples of each number.
• What is changed at the bottom must be changed at the top of a fraction.
• Subtract the new numerators: 10-3= 7

140

Example: 5 2/3 - 3 4/5=

5 2/3 multiply 5= 10/15

(5-1=4) 10/15 + 15/15= 25/15

4 25/15+ 3 12/15= 1 13/15

• Burrowing whole numbers from whole numbers, find the LCD.
• 10 cannot subtract from 12; therefore 1 must be borrowed from the whole number making it 4, and the borrowed number must be added to the

141

Example: 20/13=

1 7/13

• For multiplying improper fractions multiple top times top and bottom times bottom.
• To change a improper fraction into a mixed number, divide the numerator(top) by the denominator (bottom).
• 13/20= 1 7/13

142

Example: 4/5 x 1/2=

4/10

• Multiply the numerators together: 4x1
• Multiply the denominators together: 5x2
• Reduce the product by using the greatest common factor: 4/10 divided by 2 top and bottom = 2/5

143

Example: 5 x 4/13 =

5/1 x 4/13= 20/13 = 1 7/13

• Make the whole number 5 into a far action by placing 1 as the denominator.
• Multiply the numerators together: 5x4
• Multiply the denominators together: 1x13
• Change the improper fraction into a mixed number.

144

Example: 2 1/8x 7 5/6=

2 1/8 x 7 5/6=
8 6
17/8 x 47/6= 799/48

799/48= 16 31/48

• Change the mixed numbers into improper fractions. 8x2+1= 17 and 6x7+5=47
• Multiply the numerators and denominators together: 17x47=799 and 8x6=48
• Change the improper fraction into a mixed number: 48/799

Alex had six friends who each give him 2 3/4 pieces of gum. How many pieces of gum does Alex have now?

16 1/2

154

Example: 1/2 / 3/8=

1/2 / 3/8 = inverse (3/8) to 8/3

• Then multiple 1/2 x 8/3= 8/6
• Change the improper fraction into a mixed number: 3 divided 8
• 3 2/2

155

Example: 1 5/6 / 3/4=

1 5/6 / 3/4= 2 4/9

• Change the mixed number into an improper fraction: 1 5/6= 11/6
• (6x1+5=11)
• Inverse the second fraction: 3/4 to 4/3
• Multiply the 11/6 x 4/3= 44/18
• Change the improper fraction into mixed number, then reduce the mixed number: 2 8/18 divided by 2 top and bottom = 2 4/9
