5.25
=5+1/4
=20/4+1/4
=21/4
----------------------------
(21/4)/(5/1)
=(21/4)*(1/5)
=21/20
=20/20+1/20
=1+0.05
=1.05
*One note book costs $1.05
--------------------------
3 note books cost:
3*$1.05
=$3.15
=5+1/4
=20/4+1/4
=21/4
----------------------------
(21/4)/(5/1)
=(21/4)*(1/5)
=21/20
=20/20+1/20
=1+0.05
