1. cm + 37. cm =?

18.000 m + 24.000 mm =?

1. l - 33. g =?

Explanation:

Step1: Analyze 77 L - 33 g

Liters (L) is a unit of volume and grams (g) is a unit of mass. Different - type units cannot be subtracted.

Answer:

no, N/A

Step2: Analyze 18.000 m+24.000 mm

First, convert 24.000 mm to m. Since 1 m = 1000 mm, then 24.000 mm=$\frac{24.000}{1000}$m = 0.024 m.
Then 18.000 m+0.024 m = 18.024 m.
