We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.
We can generate equivalent fractions by multiplying both numerator and denominator by the same number.
So, we have
Similarly, we have
Now we can sum the fractions:
we are given
we can see that
each terms are multiple of 2
so, we can factor out 2
we can divide both sides by 2
we can rearrange it
now, we can move 10 on right side
now, we can add both sides 7^2 and 5^2
we can simplify it
we can also write as

Answer:
The offices can be filled in 3,360 ways
Step-by-step explanation:
In this question, we are faced with a selection problem.
There are three offices and 3 officers to be selected.
For the first position, we are to select 1 out of 16. Now, for the second position, we are left with 15 members from which we are to select one. This is because the first selection has been picked and cannot partake in the subsequent selections.
Likewise for the third position, we are selecting 1 out of 14
The number of ways this can be done is thus; 16C1 × 15C1 × 14C1 = 16 × 15 × 14 = 3,360 ways
