What is the next fraction in this sequence? Simplify your answer.

9/20, 21/40, 3/5, 27/40 ... ?

I believe the next answer is 3/4

So first identy the type of series by looking at the relationship, in this case it is arithmetic!

So we know it adds up by the same thing everytime which is 3/40!

Next number will be ... 27/40 + 3/40 = 30/40

Simplify 30/40, divide by 10 both 30 and 40 to get ... 3/4

So next fraction is 3/4
