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

(iv) 8/9

(v) 5

**Solution:**

Numerators are:

(i) -7

(ii) 15

(iii) -17

(iv) 8

(v) 5

**Question: 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

**Solution:**

Denominators are:

(i) 5

(ii) – 34

(iii) – 82

(iv) 1

(v) 1

**Question: 3**

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

**Solution:**

According to the question:

Numerator = (-3) x 4 = – 12

Denominator = (34 – 23) x (7 – 4) =11 x 3 = 33

Therefore, Rational number = -12/32

**Question: 4**

Write the following rational numbers as integers:

**Solution:**

Integers are 7, -12, 34, -73 and 95.

**Question: 5**

Write the following integers as rational numbers with denominator 1:

-15, 17, 85, -100

**Solution:**

Rational numbers of given integers with denominator 1 are:

**Question: 6**

Write down the rational whose numerator is the smallest three digit number and denominator is the largest four digit number.

**Solution:**

Smallest three digit number = 100

Largest four digit number = 9999

Therefore rational number = 100/9999
