Double-click your home button if your device has one, then swipe up on each app. If you don't have a home button, use your finger to swipe up from the bottom, similar to how you swipe up to minimize an app. However, when you swipe up, don't release, but keep your finger on the display until the menu pops up revealing all your background apps. From there, you may swipe up on each app to close it.
