3 1/4 + 0,15 x 4/5 : 5%
= 13/4 + 0,12 x 100/5
= 13/4 + 2,4
= 130/40 + 96/40
= 216/40
= 54/10 = 27/5
72%..ke-3
4 3/5 = 23/5 = 460/100 = 460%............ke-5
8/5 = 160/100 = 160%........ke-4
0,312 = 312/1000 = 31,2% ....ke-1
5/16 = 31,25%...ke-2
210 km = 21000000 cm
21000000 : 3 = 7000000
skala = 1 : 7.000.000
tab devi = 26000 : (9-4) x 4 = 5200 x 4 = 20800
70 m = 7000 cm
skala 1:350
panjang = 7000*1/350 = 20 cm
luas = 20 x 20 = 400 cm²
