Write each fraction as the sum or difference of two terms.

16, 3n+5/7

17, 9p-6/3

18. Write an expression in simplified form for the area of the rectangle:

Solution:

16.

Given: 3n+5/7

We can rewrite it as:

3n+5/7 = 3n/7 + 5/7

The sum of two terms is 3n/7 + 5/7.

17.

Given: 9p-6/3

We can rewrite it as:

9p-6/3 = 9p/3 - 6/3

= 3p - 2

The difference of two terms is 3n/7 + 5/7.

18.

Given: Length = - 2n+17

Width = 24

Area = length * Width

= (-2n + 17) * 24

= - 48n + 408

Hence, the simplest form is - 48n + 408.
