I understand how to divide fractions by other fractions but want to know why this is a useful mathematical technique. When do you need/want to divide a fraction by another fraction? What’s it useful for? Is it a specialist thing or am I missing an obvious application?
In: Mathematics
I can eat half a pizza in a third of an hour. How long does it take me to eat a whole pizza?
1/2 pizza / 1/3 hour = 3/2 pizza/hour = 2/3 hour/pizza
I mean it may sound trite but you need/want to divide a fraction by another fraction whenever… you would need to divide a fraction by another fraction. Any time you’re dealing with something where you are dividing fractions.
