900 m – 15 m 4 dm · 4 – 560 m 40 cm : 5

Uzunliklarni santimetrga aylantiramiz: 900 m = 90 000 cm; 15 m 4 dm = 1540 cm; 560 m 40 cm = 56 040 cm.

Avval ko‘paytirish va bo‘lishni bajaramiz: 1540 · 4 = 6160 cm; 56 040 : 5 = 11 208 cm.

Endi ayiramiz: 90 000 – 6160 – 11 208 = 72 632 cm.

Javob: 726 m 32 cm.
