Answer 1

Respuesta:

5/6a - (a-1)/2a_______ mcm(6a)

5/6a - 3(a-1)/6a=

(5 - 3a +3)/6a=

(8 - 3a)/6a=

8/6a - 3a/6a=

4/3a - 1/2. R//.

2)

(a+b)/6 +(a - b) /2a

a(a+b) /6a + 3(a-b)/6a

(a²+ab)/6a +(3a - 3b)/6a

(a²+ab+3a - 3b)/6a

3)

(a+b)/6 - (a-b) /2a

a(a+b)/6a - 3(a-b)/6a=

(a²+ab - 3a +3b)/6a.
