Hmm - are you missing a 'c' in the numerator or anything?

= (5a - 5b) / (5a - 2b + c)
= (5 + 10) / (5 + 4 + 1)
= 15 / 10
= 3 / 2
I`m with you on this one !

5(1) - 5(-2) = 5 - (-10) = 15
5a-2b+c = 5(1) - 2(-2) + 1 = 5 -(-4) + 1 = 5 + 4 + 1 = 10
15/10 = 3/2
Correct

(5a-5b)/(5a-2b+c)
=(5*1-5*-2)/(5*1-2*-2+1)
=(5+10)/(5+4+1)
=15/10
=3/2
And you are perfectly correct in your answer
