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
galina1969 [7]

Answer:

Jane is 11 1/4 years old.

Step-by-step explanation:

Subtract all of the numbers given.

13\frac{5}{6} -1\frac{1}{3} -1\frac{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\frac{10}{12} -1\frac{4}{12} -1\frac{3}{12}.

Now we can subtract.

13\frac{10}{12} -1\frac{4}{12} -1\frac{3}{12}=11\frac{3}{12}

Reduce the answer.

11\frac{3}{12}=11\frac{1}{4}

In decimal form 11.25

Hope this helps!

If not, I am sorry.

14(4n - 5)

Step-by-step explanation:

The GCF of 56 and 70 is 14

56/14 = 4

14(4n - 5)
