In the given case, write the rational number whose numerator and denominator are respectively as under:
25 + 15 and 81 ÷ 40

Solution:

It is given that

25 + 15 and 81 ÷ 40

Consider the numerator

p = 25 + 15 = 40

Denominator q = 81 ÷ 40 = 81/40

p/q = 40/ (40/81) = 1/81

Therefore, the rational number is 1/81.

✦ Try This: In the given case, write the rational number whose numerator and denominator are respectively as under:

20 + 10 and 80 ÷ 40

It is given that

20 + 10 and 80 ÷ 40

Consider the numerator

p = 20 + 10 = 30

Denominator q = 80/40 = 2

p/q = 30/2

Therefore, the rational number is 30/2.
