Question

convert each measure into the units asked for 3 m 7 km to cm​

Answer 1

Answer:

a) we know that

1km=1000m

Hence,

Using unitary method

7km=7×1000m

7km=7000m

(b) we know that

1m=100cm

Hence,

Using unitary method

4m=4×100cm

4m=400cm

Answer:

3 meter = 300 cm and 7 km = 700000 cm
