A battery that lasts for 12 hours
has been in use for 7 hours. What
percent of the battery life has been
used up?

To find out how much of the battery life has been used up, you can divide the time the battery has been in use by its total life and multiply by 100. So, 7 hours ÷ 12 hours = 0.583. Multiply by 100 to convert it to a percentage: 0.583 × 100 = 58.3%. Therefore, approximately 58.3% of the battery life has been used up!

For a fun twist, imagine you’re on a mission with a gadget that only has 12 hours of juice. After 7 hours of scrolling, gaming, or binge-watching, you’ve used up a bit more than half your superhero power! Keep an eye on it – you don’t want to run out just before the big reveal!
