= -b ANSWER

teddy boy

= (5a - 5a - 5b - 5b)/10
= - 10b/10
= - b

Answer: - b

(ab+b²)/(4ab?) / (a+b)/(6a²b?) = (ab + b²)/(4ab?) × (6a²b?)/(a + b) ......................................... = b(a + b)/ × (6a²b?)/(a + b) ......................................... = b(a + b)/(a + b) × (6a²b?)/(4ab?) ......................................... = b × (3a)/(2b) ......................................... = 3a/2

(- 10 b) / 10 = - b

(5a - 5a - 5b - 5b)/10
= (0 - 5b - 5b)/10
= (-5b - 5b)/10
= -10b/10
= -b

Do the top of the fraction first
5a - 5a = 0
-5b - 5b = -10b
So you have -10b/10. Divide top and bottom by 10
= -b

5a-5a-5b-5b over 10

Solution

Separate the terms

5a/10 = 1/2a
-5a/10= -1/2a
-5b/10= -1/2b
-5b/10= -1/2b

Then Write out and combine like terms

1/2a-1/2a-1/2b-1/2b
so the a's cancel out and combine the b's
answer = -b

-10b/10-> -b

5a - 5a = 0
-5b - 5b = -10b

So fraction is (0 - 10b)/10 = -10b/10
= -b
