If (a+b) / (x−y) = 3/5 then (10a + 10b) / (9x−9y) = ?
lbvjy [14]

Answer:

2/3

Step-by-step explanation:

Look at what you are getting on the right hand question. 10a +10b has a common factor that can be pulled out. It is 10

10a + 10b = 10(a + b)

Now look at the denominator

9x - 9y = 9(x -y)

There are a lot of possible answers.

Mine would be to multiply 3/5 * 10/9

\dfrac{3}{5}*\dfrac{10}{9} = \dfrac{30}{45} = \dfrac{2}{3}

so

(10a + 10b)/(9x - 9y) = 2/3
