Let me give the significations following
natural numbers :ACA counting numbers the numbers you naturally say when counting.
whole numbers: include all natural numbers zero
Integers: include all whole numbers and their opposites.
Rational: can be written ASA fraction or ratio of two integers also decimals that terminate or repeat
Irrational: can not be written a fraction, decimals, do not terminate or repeat.
Answer:
Triangle is a three(3) sided shape i.e it has 3 sides and angles. Triangle can classify based on its side (length and equality) and size of its angles.
Step-by-step explanation:
A, Classification by sides: There are three types of triangle base on sides. These are:
1. Scalene Triangle : This describe triangle that has none of its side to be equal. i.e none of the three sides has no equal length.
2. Isosceles Triangle : This describe triangle that has two of its side equal. Also two of the angles are equal.
3. Equilateral Triangle : This describe triangle that has all its side equal i.e all three sides have equal length. Also all angles are of equal sizes.
B. Classification by size of angle: There are four types of triangle base on classification by angle:
1. Acute Triangle : This describe triangle with all three angles less than 90 degree.
2. Obtuse Triangle : This describe triangle that has one of its angle greater than 90 degree
3. Right Angled Triangle : This describe triangle with one of its angle equal 90 degree.
The last pair of numbers bracket the point 3/7.
12/32 = 3/8 < 3/7
15/18 = 5/6 > 3/7
_____
3/7 ≈ 0.428571... (repeating), so will be larger than 3/8 = 0.375, 12/32 = 3/8, and 4/10. That is, 3/7 is larger than the largest number of each pair except the last.
------
You can always compare two fractions to see which is larger by cross-multiplying. That is a/b vs c/d gives the same result as ad vs bc. (Put the product on the numerator side of the comparison.)
Here, that would mean comparing 12/32 vs 3/7, we would get 12·7 vs 3·32, or 84 vs 96. The fraction on the left is smaller.
Comparing 3/7 vs 15/18, we would get 3·18 vs 7·15, or 54 vs 105. The fraction on the right is larger.
160,582 = 100,000 + 60,000 + 500 + 80 + 2

Lets make x and y the two numbers. The sum of the two numbers (x and y) is 9 means that they add to 9. So the first equation is
x+y = 9
Let's isolate y by subtracting x from both sides. That gives us
y = 9-x
The other bit of information given is "if one number is subtracted from the other, the result is -1", which means we have this other equation
x-y = -1
From here, substitute y for 9-x
x-y = -1
x-(y) = -1
x-(9-x)=-1
x-9+x=-1
2x-9 = -1
2x-9+9 = -1+9
2x = 8
2x/2 = 8/2
x = 4
If x = 4, then y is...
y = 9-x
y = 9-4
y = 5
Therefore, the two numbers are 4 and 5. They add to 9
4+5 = 9
and they subtract to -1
4-5 = -1
Final Answer: 4 and 5
