## What you’ll learn to do: Use properties to solve equations that contain fractions

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 $\Large\frac{7}{12}$ 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 $x$ equal the total number of people in her office and then set up an equation involving fractions to solve for $x$. We’ll explore how to do that in this section.
