Answer:
1/8
Explanation:
Anytime you need to divide and there's a fraction involved, like a fraction over a number (like your question) or a number over a fraction, or even a fraction over a fraction, you can use this method.
Keep-Change-Flip
Keep the first or top number the same. Change the divide to a times. Flip the second number. Then you can multiply. For multiplying with fractions, you multiply top×top and bottom×bottom, straight across. See image.
