Answer:

7/40

Step-by-step explanation:

To subtract 2 fractions, we can use the following equation:


(a)/(b)-(c)/(d)=((a* d)-(b* c))/((b* d))

Then, 5/8 - 9/20 will be equal to:


(5)/(8)-(9)/(20)=((5*20)-(8*9))/(8*20)=(100-72)/(160)=(28)/(160)

Finally, simplify the fraction dividing by 4, so:


(28)/(160)=(28/4)/(160/4)=(7)/(40)

Therefore, the answer is 7/40
