2. 5-8=3
yahya= 5/3 × 210.000 = 350.000
ilham= 8/3 × 210.000 = 560.000
jumlah = 350.000 + 560.000 = 910.000

3. 10+7 = 17
ali = 10/17 × 510.000 = 300.000
eli = 7/17 × 510.000 = 210.000
selisih = 90.000

4. 4+1= 5
panjang = 4/5 × 50 = 40:2 = 20 cm
lebar = 1/5 × 50 = 10 : 2 = 5 cm
luas = panjang × LEBAR = 20 × 5 = 100 CM
