Answer 2

Step-by-step explanation:

$\huge\underline\mathfrak\color{blue} Answer$

b] 3.171717 is in an irrataional form, we will have to convert it into rational to get it into p/q form.

3.171717 has the recurring decimal in 2 points.

So, let us take this number as x

Then, lets multiply the number with 100 as it has two decimal recurring points.

Then,

x = 3.1717

x = 3.1717100x = 317.17

x = 3.1717100x = 317.17100x = 317.17

x = 3.1717100x = 317.17100x = 317.17x = 3.1717

Let's subtract both the equations.

99x = 314

99x = 314x = 314 / 99

p/q form of 3.1717171717 is 314/99

________________________________

c] let x = 15.89 .... (1)

multiplying both sides by 100 we get=

100x= 1589.89. =. ......(2)

subtracting (1) from (2) we get=

99x= 1574

$x = \frac{1574}{99}$

so hence 3.17=

$\frac{1574}{99}$
