Respuesta :

0.5 kg ( from different country)

Answer: 5,700 mg

Step-by-step explanation: First, put all the measurements at the same unit. I chose g.

25 mg = 0.025g

120 g = 120 g

0.5 kg = 500 g

5,700 mg = 5.7 mg

We can rule out 120 g and 500 g because it would be too heavy for a coin. 0.025 g is too light for a coin. This way, we can choose the 5.7 g
