Let "a" represent Alondra's number. Then the math she performs on it is ...
2a-6 . . . .double my number and subtract 6
| 2a-6 | < 2 . . . . . the result is less than 2 units from zero
This absolute value expression can be "unfolded" to two of them ...
-2 < 2a -6 < 2
Dividing by 2 gives ...
-1 < a -3 < 1
Adding 3, we get ...
2 < a < 4
The only whole number in this range is ...
a = 3
Alondra is thinking of the number 3.

Answer and explanation:
The ratio 1:2 is different from the ratio 2:1. The ratio 1:2(one to two) means a comparison of two sizes; the ratio of one part of that thing to the ratio of two parts of that thing. Likewise, the ratio 2:1 is the comparison of two parts of a thing to the ratio of one part of the thing. For the ratio 2:1, we could say for example that for every two crushed tomatoes there is one tomato paste.
