, Question 1
1.1 What name is attached to the numbers crossed except one? (1)
The name attached to the numbers crossed except one is composite
numbers.
1.2 Which method was used to identify prime numbers in the years 262-190 BCE? (1)
The method used to identify prime numbers in the year 262-190 BCE was the
Sieve of Eratosthenes.
There are five regular convex platonic solids.
1.3 Name and describe all the properties of any of the five solids. (3)
One of the five regular convex Platonic solids is the tetrahedron, which has
four faces that are equilateral triangles, and each vertex is shared by three
faces.
The Egyptians used the approximated process to work on the area of a circle as
shown in the picture.
1.4 Show the representation of the fractions on the second row. (2)
The representation of the fractions on the second row is 1/8, 2/8, 3/8, 4/8, 5/8,
6/8, 7/8.
1.5 Show the algorithm/abstract strategy to justify the 3/5 found as the answer. (3)
The algorithm/abstract strategy used to justify the 3/5 found as the answer is
to divide the circle into 10 equal parts (since there are 10 rows), shade 6 parts
(since 6 rows have been shaded), and then simplify the resulting fraction,
which is 6/10 or 3/5.
The table on the left shows the Chinese numbering system.
1.6 Write down the number 7 429 using these symbols. (2)
The number 7 429 in the Chinese numbering system is represented as 七千四
百二十九.
In this picture, there are 52 balls,
