(i) 4.3 `xx` 0.13 =? (ii) 1.12 `xx` 2.3 `xx` 4.325 =?

Answer

Let's solve the given questions step by step.

### Question (i): 4.3 `xx` 0.13

**Step 1:** Rewrite the numbers in fractional form.
- \( 4.3 = \frac{43}{10} \)
- \( 0.13 = \frac{13}{100} \)

**Step 2:** Multiply the fractions.
- \[ 4.3 \times 0.13 = \frac{43}{10} \times \frac{13}{100} = \frac{43 \times 13}{10 \times 100} \]

**Step 3:** Calculate \( 43 \times 13 \).
- \( 43 \times 13 = 559 \)

**Step 4:** Substitute back into the fraction.
- \[ \frac{559}{1000} \]

**Step 5:** Convert to decimal form.
- \[ \frac{559}{1000} = 0.559 \]

### Final Answer for (i):
\[ 4.3 \times 0.13 = 0.559 \]

### Question (ii): 1.12 `xx` 2.3 `xx` 4.325

**Step 1:** Rewrite the numbers in fractional form.
- \( 1.12 = \frac{112}{100} \)
- \( 2.3 = \frac{23}{10} \)
- \( 4.325 = \frac{4325}{1000} \)

**Step 2:** Multiply the fractions.
- \[ 1.12 \times 2.3 \times 4.325 = \frac{112}{100} \times \frac{23}{10} \times \frac{4325}{1000} \]

**Step 3:** Combine the fractions.
- \[ = \frac{112 \times 23 \times 4325}{100 \times 10 \times 1000} \]

**Step 4:** Calculate \( 112 \times 23 \).
- \( 112 \times 23 = 2576 \)

**Step 5:** Now multiply \( 2576 \times 4325 \).
- \( 2576 \times 4325 = 11141200 \)

**Step 6:** Substitute back into the fraction.
- \[ \frac{11141200}{1000000} \]

**Step 7:** Convert to decimal form.
- \[ \frac{11141200}{1000000} = 11.1412 \]

### Final Answer for (ii):
\[ 1.12 \times 2.3 \times 4.325 = 11.1412 \]
