Question

12dam+2hm = ?m
8km+15dam?m
52hm -110dam =?m
8m+124dm?m
70dm+18cm=?mm
3000cm=180dm=?m
85dam-13m=?dm
5hm-82m=?dm
84km -15dam=?m

Answer 1

12 dam-2 hm=120 m-200 m=320 m
8 km+15 dam = 8000 m+150 m=8150 m
52 hm-110 dam=5200 m-1100 m=4100 m
8 m+124 dm=8 m+12,4 m=20,4 m
70dm+18 cm=7000 mm+180 mm=7180 mm
3000 cm-180 dm=30 m-18 m=12 m
85 dam-13m=8500 dm-130 dm=8370 dm
5 hm-82 m=500 dm-8,2 dm=491,8 dm
84 km-15 dam=8400 m-150 m=8350 m
