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

Back

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

What is the least common denominator (LCD) of the fractions \( \frac{5}{24} \) and \( \frac{1}{3} \)?

Back

The least common denominator (LCD) of \( \frac{5}{24} \) and \( \frac{1}{3} \) 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 \( 5 + 24c = 8 \), how do you solve for \( c \)?

Back

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