1.9/9 - 6/9 =?
2.3/6 - 4/8 =?
3.5/4 + 3/4 =?
4.20/20 - 9/20=?
5.2/3 - 5/9 =?

Sagot :

Answer:

1. 9/9 - 6/9 = 3/9 or 1/3

2. 3/6 - 4/8 = 0

3. 5/4 + 3/4 = 8/4

4. 20/20 - 9/20 = 11/20

5. 2/3 - 5/9 = 1/9

Step-by-step explanation:

1. (like denominators)

9/9 - 6/9 = 3/9 or 1/3 (lowest term)

2. LCM of 6 and 8 is 24

4 x (3/6) -  3 x (4/8) = 12/24 - 12/24

= 0

3. (like denominators)

5/4 + 3/4 = 8/4 or 2/1 (lowest term)

4. (like denominators)

20/20 - 9/20 = 11/20

5. LCM of 3 and 9 is 9.

3 x (2/3) - 1 x (5/9) = 6/9 - 5/9

= 1/9

Answer:

1) ⅓

2) 0

3)2

4) 11/20

5)1/9

Step-by-step explanation:

1) 9/9 - 6/9

= 9 - 6

¯¯¯¯¯¯¯¯¯¯

9

= 3/9

= 3 ÷ 3

¯¯¯¯¯¯¯¯¯¯

9 ÷ 3

= ⅓

2) 3/6 - 4/8

= 3 × 4 4 × 3

¯¯¯¯¯¯¯¯ - ¯¯¯¯¯¯¯

6 × 4 8 × 3

= 12/24 - 12/24

= 12 - 12

¯¯¯¯¯¯¯¯¯¯¯

24

= 0/24 or

= 0

3) 5/4 + 3/4

= 5/4 + 3/4

= 5 + 3

¯¯¯¯¯¯¯

4

= 8/4

= 8 ÷ 4

¯¯¯¯¯¯¯

4 ÷ 4

= 2

4) 20/20 - 9/20

= 20 - 9

¯¯¯¯¯¯¯¯¯¯

20

= 11/20

5) 2/3 - 5/9

= 2 × 3 - 5/9

¯¯¯¯¯¯¯

3 × 3

= 6/9 - 5/9

= 6 - 5

¯¯¯¯¯¯¯

9

= 1/9
