If a person is 115kg on the moon what is his weight on earth

if the mass on moon is 115kg, then his weight on earth is 1127N

But if your data is referring to his weight and not his mass as 115kg, then his weight on earth would be 704.375N

Explanation:

Weight = mass * acceleration due to gravity

On moon, his weight is 115N,

W = m*g

115 = m * 1.6

M = 115 / 1.6

M = 71.875kg

Weight on earth = mass * acceleration due to gravity on earth

Weight = 71.875 * 9.8

W = 704.375N

NB: the question isn't correct because the mass of a body remains the same irrespective of where measured, but the weight differs because of acceleration due to gravity
