Practice the questions given in the worksheet on rational numbers.

We know, numbers that can be expressed in the form x/y, where y is a non - zero integer and x is any integer are called rational numbers.

The questions are based on rational number, useful results on rational number, positive rational number and negative rational number.

**1.** Write down the
numerator of each of the following rational numbers:

(i) (-7)/5

(ii) 15/(-4)

(iii) (-17)/(-21)

(iv) 8/9

(v) 5

**2.** Write down the
denominator of each of the following rational numbers:

(i) (-4)/5

(ii) 11/(-34)

(iii) (-15)/(-82)

(iv) 15

(v) 0

**3.** Write down
the rational number whose numerator is (-3) × 4, and whose denominator is (34 - 23) × (7 - 4).

**4.** Write the following rational numbers
as integers:

17/1, (-23)/1, 35/1, (-77)/1, 91/1.

**5.** Write the
following integers as rational numbers with denominator 1:

-19, 27, 71, -101.

**6.** Write down the rational number whose
numerator is the smallest four digit number and denominator is the largest five
digit number.

**7****.** Separate positive and negative
rational numbers from the following rational numbers:

(-5)/(-7), 12/(-5), 7/4, 13/(-9), 0, (-18)/(-7), (-95)/116, (-1)/(-9)

**8.** Which of the
following rational numbers are positive?

(i) (-8)/7 (ii) 9/8 (iii) (-19)/(-13) (iv) (-21)/13

**9.** Which of the
following rational numbers are negative?

(i) (-3)/7 (ii) (-5)/-8 (iii) 9/(-83) (iv) (-115)/-197

**10.** Which is
the following statement are true or false?

(i) Every whole number is a rational number.

(ii) Every integer is a rational number.

(ii) 0 is a whole number but it is not a rational number.
