Question

Vera is using her phone. It's battery life is down to 1/2, and it drains another 1/8 every hour. How many hours will her battery last?

Answer 1

Answer: 4 is not the answer i tried it. 4 is the wrong answer the actual answer is 18/5

Explanation:

Answer 2

Her phone battery only has 1/2 left.
1 hour = 1/8.

To find how many hours there are left, divide 1/2 by 1/8. This is because you want to find out how many 8ths of battery you have left before going to 0%.

1/2 divided by 1/8 = 4.

4 hours left
