Answer 1

Answer: Choice C)
`(8)/(9)n - 1(1)/(3)`

====================================================

Step-by-step explanation:

We multiply the outer term 4/9 with each term inside

• (4/9) times (2n) = (4*2n)/9 = (8n)/9 = (8/9)n
• (4/9) times (-3) = (4*(-3))/9 = -12/9 = -4/3

The improper fraction 4/3 converts to the mixed number 1 & 1/3

4/3 = (3+1)/3 = 3/3 + 1/3 = 1 + 1/3 = 1 & 1/3

So overall, we can say
`(4)/(9)(2n-3) = (8)/(9)n - 1(1)/(3)`

This is equivalent to saying
`(4)/(9)(2n-3) = (8)/(9)n - (4)/(3)`
