Answer:

#4/5#

Explanation:

#80%# is the same thing as #80# out of #100#, which can be written as a fraction as #80/100#.

However, this can still be simplified, Since both of them are still divisible number. That number we want to divide both numerator and denominator by is called the GCF , or Greatest Common Factor .

First, let's list out the factors of #color(blue)80#:
#1, 2, 4, 5, 8, 10, 16, 20, 40, 80#

Now the factors of #color(blue)100#:
#1, 2, 4, 5, 10, 20, 25, 50, 100#

Now we find the largest factor of both numbers. That factor is #color(blue)20#.

So we divide both numerator by #color(blue)20#:
#80/100 color(blue)(-: 20/20)#

Which equals:
#4/5#

Hope this helps!
