Answer :
15 into thirds would be 15 divided by three. This would be 5. If you take 14 and divide it in half you get 7. Then subtract 5 from 7 and you get 2. The answer is 2.
Let
A------> [tex] 15 [/tex] into thirds
B------> [tex] 14 [/tex] divided in half
we know that
[tex]A=\frac{15}{3}\\\\ A=5\\\\ B = \frac{14}{2}\\\\ B=7[/tex]
so
the expression is equal to
[tex]expression=B-A\\expression=7-5\\\\expression=2[/tex]
therefore
the answer is
The expression is equal to [tex] 2[/tex]
