q1.3.6:
I started out by ""guessing and testing"". I first guess that there were three 11 year old horsed. The result to that would be 89 and that is not divisible to 9. So I kept guessing the amount of 11 year old horses to get a number divisible by 9. I finally did by guess that there were seven 11 year old horses which would result to 45 and 4 divided by 9 is five to conclude that there are five 9 year old hours and seven 11 year old horses.

q1.3.10:
Well I first added all the numbers on the clock up to get 78. So 78 divided by 3 is 26. So I then had to figure out the three segments that each would add up to 26. The numbers in the three segments would be: 11,12,1,2; 3,4,9,10; and 6,7,8.

q1.3.18:
It took me a while to get this one but I decide to start with the Friday because that information of acorns is already given to us. So if 35 acorns were left on Friday then we would realize that they had 70 to begin with because we have to add 35 because we know half were eaten. So since they brought in 32 then 70-=32=38 and so that was what they had at the end of Thrusday. So 38 times 2(for the half that was eaten) =76 for the total of beginning Thursday. So if you keep with the equation 76-32=44. 44 times2=88 that was the total for the beginning of Wed. 88-32=56. 56 times2=112 for the beginning of Tues. and 112-32=80. 80 tiems2=160 for what they started with on Monday.

q1.3.30:
You would follow the pattern and keep the number align. The numbers would go three in between one another for the number of feet taken and brough back each day. so the frog would go seventeen days before the frog would reach the top of the well.

q1.3.52:
I would first weigh 4 and 4 to see which one wighs less because that side would contain the fake coin. Then i would split them up again and go 2 and 2 to fing the lighter side. Then split those two coins up and weigh them to find the lighter one which would be the fake coin.
