When writing 3.7272727272... as a ratio of integers, what is the common ratio?

1 answer:

5 0

The answer is: "41 / 11 " ; or, write as: " 41 : 11 " .
__________________________________________________________
Explanation:
__________________________________________________________
72/99 = (72÷9) / (99÷9) = 8/ 11 .

So, 3.727272727272... = "3 $\frac{8}{11}$ " .

→ "3 $\frac{8}{11}$ " = [(11 *3) + 8] / 11 = (33 + 8) / 11 = 41 / 11 .
__________________________________________________________
"41 / 11" cannot be simplified any further; so the answer is:
__________________________________________________________
"41 / 11 " ; or, write as: " 41 : 11 " .

Step-by-step explanation:

the second line has to be parallel (but not identical), so that the 2 lines do not cross each other, do not have any point in common.

that means it must have the same slope but a different y-intercept.

the line in the graph goes through the origin (0, 0), which makes the y-intercept = 0 (the y value when x = 0).

and we see that the points with integer coordinates seem to be e.g. (3, -2).

so, for the slope (y difference / x difference between 2 points) we use this point and the origin.

x changes by +3 (from 0 to 3).

y changes by -2 (from 0 to -2).

so, the slope is -2/3. and it is always the factor of x.

let's look at the answer options :

2x + 3y = 0

3y = -2x

y = (-2/3)x

this is the identical line, so it is wrong !

2x + 3y = 6

3y = -2x + 6

y = (-2/3)x + 2

the same slope and different y-intercept.

this is the correct solution !

2x - 3y = 9

-3y = -2x + 9

y = (2/3)x - 3

wrong slope. so it is wrong !

y = 3x + 2

wrong slope. so it is wrong !
