bentuk pecahan biasa paling sederhana dari hasil operasi hitung 3 1/4+0,15×4/5÷5%

3/4 + (15/100 x 4/5) : 5/100
3/4 + 60/500 : 5/100
3/4 + 2500/6000
3/4 + 25/60
3/4 + 5/12
9/12 + 5/12
14/12 = 7/6

3 1/4 = 13/4
0,15 = 15/100
4/5 = 4/5
5% = 5/100

= 13/4 + 15/100 x 4/5 : 5/100
= 13/4 + (15/100 x 4/5 : 5/100)
= 13/4 + ( 60/400 : 5/100) (Perkalian Silang)
= 13/4 + 12/4
= 25/4
=  6 1/4
