Final answer:
The expression "7 divided by c" is written as 7/c, which is a ratio or fraction.
Step-by-step explanation:
The expression "7 divided by c" can be written as 7/c. In this expression, 7 is the numerator and c is the denominator. When you divide by a variable, you are essentially creating a ratio or a fraction that represents how many times the variable c fits into the number 7. For instance, if c equals 3 (c = 3), then using a calculator to evaluate the expression would give us a result of 2.333... (7 divided by 3). It's important to remember that c should not be zero, as division by zero is undefined.
