* To get a numerical answer, you would need to know the sum of their ages, which was given as 48 in the original form of this question, where Old is 30, Young is 18.
When Old was 18, Young was 6; when Old was 27 (1/2 of 54), Young was 15, and Old is twice that.
If you change the sum to 32, then the ages become 20 and 12.
When Old was 12, Young was 4; when Old was 18 (1/2 of 36), Young was 10.
In each case, Old is 5/3 as old as Young and 5/8 of the sum of their ages.

Old = 2 * Young when Old was 1/2 [3 * (3 * Young)]

The original question was too long to copy in. It was: "The sum of the ages of Old and Young is 48. Old is twice as old as young was when old was half as old as young will be when young is three times as old as old was when old was three times as old as young How old is old?" There is a rather strenuous algebraic solution.The answer is :Old is 30, Young is 18When Old was 18, Young was 6; when Old was 27 (1/2 of 54), Young was 15, and Old is twice that.If you change the sum to 32, then the ages become 20 and 12.When Old was 12, Young was 4; when Old was 18 (1/2 of 36), Young was 10.In each case, Old is always 5/3 as old as Young and 5/8 of the sum.
It's not half as much, it is twice as much. And it is twice as much, precisely because 2/3 is twice as much as 1/3.
three over two or one and a half
Yes, but only in the sense that they then go on to occur three times, and four times, and five times, and ...In most places there are about 13 and a half high tides per week on average.
One-half times three gives three halves (3/2), which is the same as one and one-half.
forty-three
It is three sixteenths.
It is three sixteenths.
No, half of twice is once.
