Look at the picture and kindly let me know the answer this stuff is so confusing to me

So the answer is B, this is because 3 divided by 10 is 0.3, so to rewrite it and make it true still, we must make 10 into a fraction: 1/10 so if we were to rewrite it like this; 3/1 multiplied by 1/10, we would get the same answer, .3 If I did my math right :) Hope it helps

its kinda hard to answer this when we dont have all the information that we need.

the furthest the dog can be is 508 meters away from the house, and the closest he can be is 492 meters away from the house.
