Sara and three roommates equally share the rent on their apartment. The rent is r dollars. Which expression shows Sara's share of the rent?

Question

A.
r + 4
B.
r ÷ 4
C.
r × 4
D.
r - 4

Answer 1

To find Sara's share of the rent, we need to divide the total rent \( r \) by the number of roommates (including Sara). Since Sara has three roommates, there are a total of 4 people sharing the rent (Sara and her three roommates).

The expression that represents Sara's share of the rent is:

\[ r \div 4 \]

So, the correct answer is:

B. \( r ÷ 4 \)
