Write the predecessor of each one of the following :
`(i) 120 " " (ii) 79 " " (iii) -8 `
`(iv) -141 " " (v) -300`

Answer

To find the predecessor of a number, we subtract 1 from that number. Let's solve the question step by step.

### Step-by-Step Solution:

**(i) Predecessor of 120:**
1. Start with the number 120.
2. Subtract 1 from 120.
\[ 120 - 1 = 119 \]
3. Therefore, the predecessor of 120 is **119**.

**(ii) Predecessor of 79:**
1. Start with the number 79.
2. Subtract 1 from 79.
\[ 79 - 1 = 78 \]
3. Therefore, the predecessor of 79 is **78**.

**(iii) Predecessor of -8:**
1. Start with the number -8.
2. Subtract 1 from -8.
\[ -8 - 1 = -9 \]
3. Therefore, the predecessor of -8 is **-9**.

**(iv) Predecessor of -141:**
1. Start with the number -141.
2. Subtract 1 from -141.
\[ -141 - 1 = -142 \]
3. Therefore, the predecessor of -141 is **-142**.

**(v) Predecessor of -300:**
1. Start with the number -300.
2. Subtract 1 from -300.
\[ -300 - 1 = -301 \]
3. Therefore, the predecessor of -300 is **-301**.

### Final Answers:
- Predecessor of 120 is **119**.
- Predecessor of 79 is **78**.
- Predecessor of -8 is **-9**.
- Predecessor of -141 is **-142**.
- Predecessor of -300 is **-301**.
