6]
2 dm + 30 m
= 2 dm + ( 30 x 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

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
