=(3/8 n + 5/8 n) + 1/3 n=n+1/3n=1 1/3n

Answer 2

To simplify the expression, let's find a common denominator for the fractions. The least common multiple (LCM) of 8 and 3 is 24.

Now, let's rewrite the expression using the common denominator:

3/8 n + 5/8 n + 1/3 n

= (3/8 + 5/8 + 1/3) n

To add the fractions, we need to have the same denominator. In this case, the denominators are already the same, so we can simply add the numerators:

= (3 + 5 + 8/3) n

To add the mixed number 8/3 to the whole numbers, we need to convert it into an improper fraction:

= (3 + 5 + 8/3) n

= (24/8 + 40/8 + 8/3) n

Now, we can add the numerators and keep the denominator:

= (72/8 + 40/8 + 64/8) n

= (176/8) n

= 22n

Therefore, the simplified expression is 22n.
