An elephant has a mass of 4500 kilograms. How many mice, with a mass of 2*10-2 kilogram each, would it take to equal the mass of the elephant?

Answer:225000 mice

Step-by-step explanation:

Mass of elephant=4500kg

Mass of mice=2x10^ (-2) = 2/100 kg

Let y be there number of mice

2/100 x y=4500

2y/100=4500

Cross multiply

2y=4500 x 100

2y=450000

Divide both sides by 2

2y/2=450000/2

y=225000
