Answer: We know that :
1. The numbers other than 1 whose only factors are 1 and the number itself are called Prime numbers.
2. Numbers having more than two factors are called Composite numbers.1 and the number itself
3. 1 is neither a prime nor a composite number.
Going by the above statement it is clear 1 and the number itself, are the factors which are not included in the prime factorisation of a composite number.

The comparison of two numbers or quantities by division is known as the ratio. Symbol ‘:’ is used to denote ratio.
Four quantities are said to be in proportion, if the ratio of the first and the second quantities is equal to the ratio of the third and the fourth quantities. The symbol ‘::’ or ‘=’ is used to equate the two ratios.

3 : 8 = 3/8 = (3 × 2)/(8 × 2), [Multiply both numerator and denominator by 2]
= 6/16
= 6 : 16 is the first equivalent ratio.
3 : 8 = 3/8 = (3 × 4)/(8 × 4), [Multiply both numerator and denominator by 4]
= 12/32
= 12 : 32 is the second equivalent ratio.
3 : 8 = 3/8 = (3 × 6)/(8 × 6), [Multiply both numerator and denominator by 6]
= 18/48
= 18 : 48 is the third equivalent ratio.
Therefore, the three equivalent ratios of 3 : 8 are 6 : 16, 12 : 32 and 18 : 48.

Sum of two consecutive multiples of 17 is 85.
-
These numbers.
-
Let the two consecutive multiples of 17 be 17x and 17x + 17.
According to the Question,
17x + 17x + 17 = 85
34x + 17 = 85
34x = 85 - 17
34x = 68
x = 68/34 => 2
Therefore, x = 2
And,
17x = 17(2) = 34
(First multiple of 17)
17x + 17
= 17(2) + 17
= 17(2) + 17
= 34 + 17
=> 51
(Second multiple of 17)
Thus, the two multiples are 34 and 51.

The perimeter of a rectangle is defined as the sum of all the sides of a rectangle. For any polygon, the <a href="https://byjus.com/perimeter-formulas/">perimeter formulas</a> are the total distance around its sides. In case of a rectangle, the opposite sides of a rectangle are equal and so, the perimeter will be twice the width of the rectangle plus twice the length of the rectangle and it is denoted by the alphabet “p”. Let us derive the formula for its perimeter and area.
Suppose a rectangle has length and width as b and a, respectively.
From the definition of the perimeter we know, the perimeter of a rectangle, P = 2 ( a+b) units
where
“a” is the length of the rectangle
“b” is the breadth of the rectangle
