4. At a yard sale, Enzo sees a sign that

advertises "0.05 cents" per used book. in to a fraction

5/100 simplified to 1/20

Step-by-step explanation:

okay well 0.05 is 5 hundredths

and five hundredths is 5 out of 100

so the fraction would be 5/100

but simplified

it would be 1/20 because both 5 and 100 can go into 5 evenly 5 would turn to 1 and 100 would turn to 20
