The real numbers is the set of numbers containing all of the rational numbers and all of the irrational numbers. The real numbers are “all the numbers” on the number line. There are infinitely many real numbers just as there are infinitely many numbers in each of the other sets of numbers. But, it can be proved that the infinity of the real numbers is a bigger infinity.
The natural (or counting) numbers are 1,2,3,4,5,1,2,3,4,5, etc. There are infinitely many natural numbers. The set of natural numbers, {1,2,3,4,5,...}{1,2,3,4,5,...}, is sometimes written NN for short. The whole numbers are the natural numbers together with 00.

We have {tex}0.6 = \frac{6}{{10}}{/tex} ...(1)
Let {tex}x = 0.\bar 7 = 0.777...{/tex} ...(2)
Subtracting (1) from (2), we get
9x = 7 {tex}\Rightarrow x = \frac{7}{9}{/tex} or {tex}0.\bar 7 = \frac{7}{9}{/tex}
Now, let {tex}y = 0.4\bar 7 = 0.4777...{/tex}
{tex}\therefore \;10y = 4.\bar 7{/tex} ...(3)
And {tex}100y = 47.\bar 7{/tex} ...(4)
Subtracting (3) from (4), we get
90y = 43 {tex}\Rightarrow y = \frac{{43}}{{90}}{/tex}
{tex}\therefore \;0.4\bar 7 = \frac{{43}}{{90}}{/tex}
Now, {tex}0.6 + 0.\bar 7 + 0.4\bar 7{/tex}{tex} = \frac{6}{{10}} + \frac{7}{9} + \frac{{43}}{{90}}{/tex}{tex}= \frac{{54 + 70 + 43}}{{90}} = \frac{{167}}{{90}}{/tex}
So, {tex}\frac{{167}}{{90}}{/tex} is of the form {tex}\frac{p}{q}{/tex} and {tex}q \ne 0{/tex}.

We know the formula to find the perimeter of the circle if the diameter is given, namely π D. Substitute the diameter 4.4 and Pi value as 3.14 in the above formula. Therefore 13.82 cm is the perimeter of the given circle.

Each edge of tank = 1.5 m = 1.5{tex}\times{/tex} 100 cm = 150 cm
Area of five faces of the tank = 5 (side)2 = 5a2 = 5 (150 cm)2 = 5 (22500) = 1,12,500 cm2
Area of a square tile = 25 cm {tex}\times{/tex} 25 cm = 625 cm2
Number of tiles required = {tex}\frac{Area \ of \ five \ walls}{Area \ of \ a \ tile}{/tex} = {tex}\frac{1,12,500
}{625}{/tex} = 180 tiles ={tex}\frac{180}{12}{/tex}dozen
Cost of one dozen of tiles = ₹ 480
{tex}\Rightarrow{/tex}Cost of {tex}\frac{180}{12}{/tex}dozen tiles = ₹480{tex}\times{/tex}{tex}\frac{180}{12}{/tex}= ₹ 7,200
Hence the cost of total tiles required for tank is ₹ 7,200

For tank : l = 12 m, b = 9 m, h = 4 m
∴ Total surface area of the tank = 2(l × b + b × h + h × l)
= 2(12 × 9 + 9 × 4 + 4 × 12)
= 2(108 + 36 + 48)
= 2(192) = 384 m2
Width of the iron sheet = 2m
∴ Cost of the iron sheet = {tex}{384\over2}*5{/tex} = Rs. 960

Numbers that are not expressible as a ratio of two integers, and having an infinite and non-recurring expansion when expressed as a decimal. Examples of irrational numbers are the number π and the square root of 2.

We know that when we measure the length of a line or a figure by using a scale or any device, we do not get an exact measurement. In fact, we get an approximate rational value. So, we are not able to realize that either circumference (c) or diameter(d) of a circle is irrational. Therefore, we can conclude that as such there is not any contradiction regarding the value {tex}\pi{/tex} of and we realize that the value of {tex}\pi{/tex} is irrational.

LHS = (5+2√3)/(7+4√3)
= [(5+2√3)(7-4√3)]/[(7-4√3)(7+4√3)]
=[35-20√3+14√3-24]/[7²-(4√3)²]
=[11-6√3]/[49-48]
=11-6√3
therefore
11 - 6√3 = a + b√3
Compare both sides
a= 11, b= -6

The are infinite rational number best one to find is their mid value.
So (2 + 3/2) = 5/2

Son = x, Father = 3x
In 12 years
Son = x + 12, Father = 2(x+12) “OR” 3x + 12
2(x + 12) = 3x + 12
2x + 24 = 3x + 12
24 - 12 = x
Therefore, current age of son is 12, and father is 36.
