ANSWER - 60%
WORKING OUT
3/5 is equal to 6/10 (doubled)
Which is also equal to 60%
(Each tenth is 10%)
You lost $100 because 300-200 is 100.
First, to be able to compare these two things, you have to either find the radius of Mercury or find the diameter of the moon. I choose finding the diameter of the moon because it seems easier.
Diameter=radius*2
Diameter=1736.5*2=3473
The moon has a diameter of 3473 km.
Since Mercury's diameter, 4878km, is greater than the Moon's diameter, 3473km, Mercury is larger.
Hope this helps!
You would have to evaluate the problem so it would be 940
