1). 15 m + 8 dm = (15 × 10) dm + 8 dm = 150 dm + 8 dm = 158 dm
2). 6 m + 4 dm = (6 × 100) cm + (4 × 10) cm = 600 cm + 40 cm = 640 cm
3). 30 dm + 85 m = (30 / 10) m + 85 m = 3 m + 85 m = 88 m
4). 5 m + 50 dm = (5 × 10) dm + 50 dm = 50 dm + 50 dm = 100 dm
5). 7 dm + 60 cm = (7 × 10) cm + 60 cm = 70 cm + 60 cm = 130 cm
6). 2 dm + 30 m = 2 dm + (30 × 10) dm = 2 dm + 300 dm = 302 dm
7). 15 m + 150 dm = 15 m + (150 / 10) m = 15 m + 15 m = 30 m
8). 7 m + 300 cm = 7 m + (300 / 100) m = 7 m + 3 m = 10 m
9). 500 cm + 500 dm = (500 / 10) dm + 500 dm = 50 dm + 500 dm = 550 dm
10). 400 dm + 700 m = (400 / 10) m + 700 m = 40 m + 700 m = 740 m
