To tackle this problem I decided to work sysematically.Therefore, I first started with number 1.I looked carefully and saw the rectangle was split in half and that number 1 was a quarter of the half.The sum would be 1/4 of 1/2 which equals 1/8.Next, I looked at number 2.Easily, I could see it was a half of 1.So the answer would be 1/8 of 1/2 which equals 1/16.After that,I saw that number 3 was three times the size of number 2.The calculation would be 1/16 of 3/1. The result of this would be 3/16.Number 4 was a bit tricky.I looked at the two small triangles next to it and saw that joining them together would make number 4.This means that number 4 was a half of number 1.1/8 of 1/2 is equal to 1/16.Obviously, number 5 was a quarter of a half.1/4 of 1/2 is equal to 1/8.Number 6 was a half of number 5 so the sum was 1/8 of 1/2.This equals 1/16.
Number 7 was 3/4 of 1.The sum was 3/4 of 1/8.As a result,the answer was 3/32.8 was 1/8 - 3/32 because 3/32 plus 8 is equal would equal 1. The answer was 1/32.9 was 1/32 because it was a quarter of 5.1/8 of 1/4 is equal to 1/32.Finally, number 10 was a half of number 9. The sum was 1/32 of 1/2. The last solution was 1/64.To make sure, I added up all the calculations (including the ones that weren't numbered) and reached an answer of 1.
