Answer:
2(3x+6), 6(x+2), and 3(2x+4)
Step-by-step explanation:
This is the "commutative property of addition." The order in which you add numbers together doesn't matter, and doesn't change your final results.
Answer: The 3 is the numerator.
The top number is always the numerator.
Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.
Let, 3x is number of children.
So, 6x is number of adults and 8x is number of pensioners.
Now,
3x + 6x + 8x = 85
17x = 85
x = 5
Therefore, number of pensioners are 8×5 = 40.
Hence, this is the required solution.
