Introduction to Solving Equations That Contain Fractions

A woman writes on a notepad while two men stand nearby in an office setting Ordering lunch at the office can give you a chance to practice your math skills.
Rylee is taking lunch orders for her coworkers at the office. After taking everyone's order, she discovers that 712\frac{7}{12} of her coworkers want a burrito. If 21 people asked for a burrito, how many people is Rylee ordering lunch for altogether? To find out, we can make xx equal the total number of people in her office and then set up an equation involving fractions to solve for xx. We'll explore how to do that in this section.
