Which equation is equivalent to 6.5m?

a) 25 dm + 300cm + 1100mm

b) 3m + 25cm + 24dm + 100cm

c) 0.003km + 30cm + 21dm + 1100mm d) 3.2m + 1100mm + 12dm

d) 3.2m + 1100mm + 12dm

First, we should convert everything into meter

a) 2.5m + 3m + 1.1m

b) 3m +.25m + 2.4m + 1m

c) 3m +.3m + 2.1m + 1.1m

d) 3.2m + 1.1m + 1.2m

And it looks like answer D will give you the correct answer. If you want to know how I got the units, here's how:

1m = 10dm 1m = 10dm = 100 cm = 1000mm

1dm = 10cm

1cm = 10mm
