• 1/8 – 1⁄4 + 1/16 = • 1/8 X 1⁄4 =

• 1/16 % 1/4 =

• 1/8 – ( 1/16 x 1⁄4) =

Answer 1

1. 1/16 + 1/8

mmc

16 , 8 2

8 , 4 2

4 , 2 2

2 , 1 2

1 , 1 / 2 . 2 . 2 . 2 = 16

1/16 + 2.1/16

1/16 + 2/16

3/16

2. 1/8 - 1/4 + 1/16

mmc

8 , 4 , 16 2

4 , 2 , 8 2

2 , 1 , 4 2

1 , 1 , 2 2

1 , 1 , 1 / 2 . 2 . 2 . 2 = 16

2.1/16 - 4.1/16 + 1/16

2/16 - 4/16 + 1/16

-2/16 + 1/16

-1/16

3. 1/8 . 1/4 = 1/32

5. 1/8 - (1/16 . 1/4)

1/8 - 1/64

mmc

8 , 64 2

1 , 8 2

1 , 4 2

1 , 2 2

1 , 1 / 2 . 2 . 2 . 2 . 2 . 2 = 64

8.1/64 - 1/64

8/64 - 1/64
