Linear Equations : Solving Equations with Fractions Quiz
Quiz
*Theme/Title:
Solving Equations with Fractions
* Description/Instructions
When dealing with fractions in linear expressions, it is important to remember the least common multiple (LCM). The LCM is the smallest number that is divisible by each of the fractions in a problem.
Example:
2/3x - 1/4 = 1/2 The LCM of 3, 4, & 2 is 12.
12(2/3x - 1/4 = 1/2) Distribute the 12.
8x - 3 = 6
8x - 3 + 3 = 6 + 3 Add 3 to both sides.
8x = 9 Divide both sides by 8.
x = 8/9
For the following quiz, you will need a pencil, scratch paper and a calculator. You must solve for "x." Select the best answer from the choices.
