Question

the united states uses 24%of the worlds supply of energy.what fraction of the worlds energy is this??

Answer 1

A percentage is just a fancy version of a percentage, a percentage is always out of 100 remember, so 24% would be equal to 24/100
we aren't done because we have to simplify
24/100, divide both sides by 2
12/50
again divide by 2
6/25
you can not simplify anymore so we can conclude that the US uses 6/25 of the world's energy
