- The clock one was the hardest out of all(46 votes)
- It would seem as though for each one we take the number of times (it occurs) / the number of objects there are.
In the clock problem (between 7 o'clock and 10 o'clock, there is 3 hours) we know that a clock has 12 hours which can be written as 3/12 -> 1/4. 360 / 4 = 90(13 votes)
- The clock problem is the one I found easiest except for the worm problem. Is this just me or...?(16 votes)
- honestly i found the clock problem to be the hardest(16 votes)
- This doesn't make any sense whatsoever. It has to make at least one full turn to get to another hour. Plus another 30 degrees to get to the next hour! How is 90 degrees possible? I went through a ton of trying to solve this problem. How is 90 degrees even the answer?(17 votes)
- That's why I have a hard time with this.(3 votes)
- i kinda don't get it but I went threw it because I tried my best!(20 votes)
- For me the pizza one was hardest because I can't understand that. Anyone agrees?(20 votes)
- lol anybody now the caterpillar one(0 votes)
- this does not make any sense!!(15 votes)
- How do you remember the compass North, East, South, West because I always forget.(6 votes)
- Not (north) Every (east) Second (south) Will (west) count.The "count" doesn't matter.(1 vote)
- i don´t get the clock at all(6 votes)
- Each hour segment is = 30degrees.
Each segment looks like this, starting at the top of the clock, going clockwise (12 to 1=30degrees, 1 to 2 =30 degrees, 2 to 3 = 30 degrees, 3 to 4 = 30 degrees, 4 to 5 = 30 degrees.... and so on all the way around the clock.(4 votes)
- When people do a 90 degree angle, why do they do a square to mark where the angle is?(4 votes)
- so people can recognize right (90) angles. (I think) I also think the reason people put squares is because rectangles & squares both have only 90 degree angles.(1 vote)
- you guys could help by adding a protractor to the site.(5 votes)
