The same astronaut visited Pluto. His weight on Earth was still 170 pounds, and his weight on Pluto was only 10 pounds. He removed an ice core with a weight of 25 pounds on Pluto. What is the weight of the ice core on Earth?

Respuesta :

425 because if you put these number in fractions such a$ 170/10 with x/25 you would cross multiply 170 with 25 then divide by 10
