Please help with the question in the picture!!!

Answer 1

We have the measures:

1023 cm

2.3 m

8.72m

6430 mm

1200 mm

6.4 cm

2.5m

0.06km

Now let's write all those measures in the same unit, let's use meters.

We know that:

1cm = 0.01m

1mm = 0.001m

1 km = 1000m

Then, we can rewrie the measures as:

1023 cm = 1023*0.01 m = 10.23 m

2.3 m

8.72m

6430 mm = 6430*0.001 m = 6.430 m

1200mm = 1200*0.001 m = 1.2 m

6.4 cm = 6.4*0.01m = 0.064 m

2.5m

0.06km = 0.06*1000km = 60m

Then the order, from smallest to largest is:

6.4 cm

1200mm

2.3 m

2.5m

6430 mm

8.72m

1023 cm

0.06km
