I need help, please. Please answer all!

1. 6/6 - (1/6 + 2/6)

2. 2/3 + 1/5=

3. 3/10+1/4=

4. 5/6-3/5=

5. 1/5-1/6=

1) 1/2

2) 13/15

3) 11/20

4) 7/30

5) 1/30

Step-by-step explanation:

6/6 - 3/6 = 3/6 = 1/2

2/3 + 1/5

Lcm is 15

(2×5 + 1×3)/15 = 13/15

3/10 + 1/4

Lcm is 20

(2×3 + 5×1)/20 = 11/20

5/6 - 3/5

Lcm is 30

(5×5 - 6×3)/30 = 7/30

1/5 - 1/6

Lcm is 30

(6×1 - 5×1)/30 = 1/30

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
