Front

What is the process to clear a fraction in an equation?

Back

To clear a fraction in an equation, multiply every term by the least common denominator (LCD) of all the fractions present in the equation.

Front

What is the least common denominator (LCD) of the fractions 24 and 3?

Back

The least common denominator (LCD) of 24 and 3 is 24.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation until the variable is alone on one side.

Front

If you have the equation \( 5 + 24c = 8 \), how do you solve for c?

Back

Subtract 5 from both sides to get \( 24c = 3 \), then divide both sides by 24 to find \( c = \frac{1}{8} \).
