A person standing on Mars would weigh 38% of his earth weight. What is the Mars weight of a person with an earth weight of 55 kilograms?

20.9kg

Yes.

To calculate the weight of a person on Mars, we need to multiply their Earth weight by the proportionate weight on Mars, which is 38% or 0.38.

Here's the step-by-step calculation:

1. Multiply the Earth weight by the proportionate weight on Mars:
Weight on Mars = Earth weight * Proportionate weight on Mars
Weight on Mars = 55 kg * 0.38

2. Calculate the result:
Weight on Mars = 20.9 kg

Therefore, a person with an Earth weight of 55 kilograms would weigh approximately 20.9 kilograms on Mars.
