Question

Timothy is 13 5/6 years old. Camden is 1 1/3 years younger than Timothy and Jane is 1 1/4 years younger than Camden. How old is Jane?

Answer 1

Jane is 11 1/4 years old.

Explanation:

Subtract all of the numbers given.

`13(5)/(6) -1(1)/(3) -1(1)/(4)`.

To subtract this, we need to find a common denominator.

A common denominator in this situation is 12. To do this multiply the 5 and the 6 of 5/6 by 2. Multiply the 1 and the 3 of 1/3 by 4. And multiply the 1 and the 4 1/4 by 3.

The new expression will look like this:

`13(10)/(12) -1(4)/(12) -1(3)/(12)`.

Now we can subtract.

`13(10)/(12) -1(4)/(12) -1(3)/(12)=11(3)/(12)`

Reduce the answer.

`11(3)/(12)=11(1)/(4)`

In decimal form 11.25

Hope this helps!

If not, I am sorry.
