**CBSE CLASS 8 MATHEMATICSRational Numbers – Chapter 1/ WorksheetsFill in the blanks:**

- ———- is also known as negative of a number.
- Multiplicative inverse is also called as ————–
- Additive inverse of 0 is —————-
- A rational number between ½ and 1 is ————
- There are ———– rational numbers between any two given rational numbers.
**Answer the following:** - Write the additive inverse of (-1/4)?
- Write five rational numbers less than -2?
- Name the property under multiplication used in each of the following:

a) (-3/4) x (4/-3) = 1

b) (-1/2) x 1 = 1 x (-1/2) = -1/2 - Write in ascending order: -4/5, -7/5, 0, 8/5, 1/5, -10/5
- Multiply 4/13 by the reciprocal of (-4/26)?

**ANSWERS:**

- Additive Inverse
- Reciprocal
- 0
- ¾
- Countless
- ¼ is the additive inverse of (-1/4) because (-1/4) + ¼ = 0
- There are countless rational numbers less than -2.

Some of the rational numbers are -3, -4, -5, -6, -7 - a) Multiplicative inverse

b) 1 is the multiplicative identity - -10/5, -7/5, -4/5, 0, 1/5, 8/5
- Reciprocal of (-4/26) is (-26/4)

Product = (4/13) x (-26/4) = -2.
