#exercise 1.1

Exercise : 1.1

Question 1. Use Euclid's division algorithm to find HCF of

(i) 135 and 225

(ii) 196 and 38220

(iii) 867 and 255

Solution 1.

(i) 135 and 225

Since 225>135, we can apply Euclid's division lemma to 225 and 135

225 = 135×1 + 90

Since the remainder 90≠0 , we can apply Euclid's division lemma to 135 and 90

135 = 90×1 + 45

Again we can see that the remainder 45≠0 we will again apply Euclid's division lemma to 90 and 45

90 = 45×2 + 0

We get remainder = 0

So in last step divisor is 45 so the HCF of 135 and 225 is 45.

I do have a few sketchbooks, but I do not follow them through. I am not sure why. perhaps is because there is not one answer. Sometimes is the paper, other time is that I do not like the work inside them. 

Exercise 1.1

Illustration base on Javier Sáez Castán 

I went back and I did the exercise 1.1 again. The second illustration base on Javier Saez. I was happy with the lino cut illustration but I felt that something was missing with the second one. I still base my illustration on a sea monster that is one of this illustrators themes I used small lines, that is also something that I used a lot but I did on a wacoom rather than by hand. I based this illustration in a tutorial give by Alberto Montt. I define the space first, I did several sketchs, one for the sea, one for the city and finally for the monster. I worked all of them individually and I build the scene that way.
