we start by finding the lcm of 10 and 4, which is 20.

so we multiply 3 by 2 and get 6.

Then, we multiply 1 with 5 and get 5.

Lastly, we add 6 and 5 to get 11/20 so 11/20 is the answer

I found another website with the same problemand the answer:

88 people, 13 with none, so 88-13 = 75

Thus 50 have fur, 25 fangs.

Just simple kinematics,

Jack = v1 = 60 mph

Joe = v2 = 30 mph

t = 10 min = 1/6 hr

Jack Dist = (60 mph) * (1/6 hr) = 10 miles

Joe Dist = (30 mph) * (1/6 hr) = 5 miles

Total Distance Between = 15 miles

If you have trouble imagining points starting from some unknown and traveling to a mid point, just imagine it as if they started from some point then traveled away in the same manner, how far apart the would be.

thanks Cphill, you and many other people have answered many of my problems so thank you to you all

The entire triangle itself will have an area of 16, because the side length of the entire triangle is 4, so 4x4=16. 

Then, we'll have to find the area of the space that is NOT the stacked squares.

If you look closely there are two half-triangles to accompany each square so we can put them together and if you look even MORE closely, all of the side triangles equal HALF of all of the stacked squares combined.

I hope this gave you a clue, but I am warning you that I am not exactly great at math and let alone geometry.
