1. 200 cm-70 cm =... cm 2. 400 cm+200 cm=... m 3. 80 m -200 cm=... cm

1.200cm-70cm=130cm
2.400cm+200cm=600cm=6m
3.80m-200cm=........cm
8000cm-200cm=7800cm

semoga membantu

1. 200 cm - 70 cm = 130 cm
2. 400 cm + 200 cm = 600 cm
[1 m = 100 cm.]
(dibalik pun sama, karena naik dibagi)
= 600 ÷ 100 = 6 m
3. 80 m = 80 × 100 = 8000 cm
= 8000 - 200 = 7800 cm
