Jawab:
belanjaan nani:
kopi=3 1/2/1/4×RP 3.000,-
=7/2×4×RP 3.000,-
=7×2×RP 3.000,-
=14×RP 3.000,-
=RP 42.000,-
gula=4 3/4/1/4×RP 14.000,-
=19/4×4×RP 14.000,-
=RP 266.000,-
total belanjaan=gula+kopi
=RP 266.000,-+RP 42.000,-
=RP 308.000,-
uang kembalian=RP 100.000,- -total belanjaan
=RP 100.000,- -RP 308.000,-
=-RP 208.000,-
artinya uang nani kurang RP 208.000,-
