[tex] \frac{a + 2b}{a - 2b} = \frac{ \frac{a}{b} + 2 \frac{b}{b} }{ \frac{a}{b} - 2 \frac{b}{b} } = \frac{ \frac{3}{7} + 2 }{ \frac{3}{7} - 2 } = \frac{ \frac{17}{7} }{ - \frac{11}{7} } = - \frac{17}{11} [/tex]

Answer:

If a/b = 3/7 which of the following is equal to (2a+4b)/(2a-4b)?

The answer is -17/11 but im trying to figure out how

Step-by-step explanation:

a / b = 3/7; (2a + 4b) / (2a-4b)

Replace the values of a and b:

(2x3) + (4x7) / (2x3) - (4x7)

6 + 28/6 - 28

34 / - 22

We simplify dividing each term by 2 and we have left: - 17/11
