1 3/5 x 35% = 8/5 x 35/100 = 280/500 = 14/25 hektar

misal uang yuli sebelumnya = x
pensil = 1/10 x
pulpen = 1/5 x
buku = 1/2 x
sisa uang yuli = x – 1/10 x – 1/5 x – 1/2x
= 10/10x – 1/10x – 2/10x – 5/10x
= 2/10x
= 1/5x
1/5x = 2.000.000
x = 5 x 2.000.000
x = 10.000.000
maka
pensil = 1/10 x 10.000.000 = 1.000.000
pulpen = 1/5 x 10.000.000 = 2.000.000
buku = 1/2 x 10.000.000 = 5.000.000
