c) 57 m
d) 500 m
e) 7.5 m
f) 57 m
Step-by-step explanation:

1 dam = 10 m
1 km = 1000 m
100 cm = m
Correct ☑ ✔ Question :-
Transform in metre
a) 7 dam
b) 350 dm
c) 57000 mm
d) 0.5 km
e) 750 cm
f) 5.7 dam
<h3>Solution ✔</h3>
a) 7 dam
1 dam = 10 m
so, 7 dam = 7 × 10 m = 70 m
b) 350 dm
10 dm = 1 m
so, 350 dm = 350/10 = 35 m
c) 57000 mm
1000 mm = 1 m
so, 57000mm = 57000/1000 = 57 m
d) 0.5 km
1 km = 1000 m
0.5 km = 1000 × 0.5 = 500 m
e) 750 cm
100 cm = 1 m
750 cm = 750/ 100 = 7.5 m
f) 5.7 dam
1 dam = 10 .
5.7 dam = 5.7 × 10 = 57 m
