Answer:
1:3
Step-by-step explanation:
To answer this, since the resulting numbers are equal, we can choose any arbitrary number for the resulting number.
Let the resulting number be 100.
As deduced from the question, A is increased by 50%, this means before the increment, A had a value of 66(2/3), an increment of 33(1/3) gave its present value.
Now, we were told that B was decreased by 50%, this means initially, B was at a value of 200.
Now the ratio of A to B is:
66(2/3) to 200
Converting A to improper fraction will yield 200/3.
The ratio is thus
200/3 : 200
This is same as
1/3 : 1 or simply 1:3
