Possible Ages Sum of The Ages 1 2 36 391 4 18 231 8 9 181 3 24 282 3 12 172 4 9 152 6 6 142 2 18 223 3 8 143 4 6 13

The sum has to be 14. So it can be 2, 6, and 6 or 3, 3, and 8.
But it cannot be 3, 3, and 8 because the youngest cannot be a twin.

So it is 2, 6, and 6.

Hope this helps :)

Answer:

The answer rounded to the nearest whole number is 1729

Step-by-step explanation:

Set it up like this: Percent in fraction form = x over total

So: 34/100 = x/5086

You then multiply: 34 x 5086 = 172924

Then divided that number by 100: 172924 divided by 100 = 1729.24

Then round the number to the nearest whole number: 1729

Hope this helps good luck!
