Răspuns:
a/b=6 rezulta ca a=6b
a)a+b/b=6b+b/b=7b/b=7
b)a+b/a=6b+b/6b=7b/6b=7/6
c)b/a+b=b/6b+b=b/7b=1/7
d)a-b/b=6b-b/b=5b/b=5
e)a-b/a=6b-b/6b=5b/6b=5/6
f)a/a-b=6b/6b-b=6b/5b=6/5
g)a+b/a-b=6b+b/6b-b=7b/5b=7/5
h)2a+5b/5b=2*6b+5b/5b=17b/5b=17/5
i)3a+4b/5b=3*6b+4b/5b=22b/5b=22/5
j)8a-3b/5b=8*6b-3b/5b=45b/5b=45/5=9
