Find
(i) `12/25` of a liter
(ii)`5/8` of a kilogram
(iii)`3/5`of an hour

Options

A. `"490 ml, 620 g, 59 min"`
B. `"480 ml, 625 g, 36 min"`
C. `"400 ml, 605 g, 72 min"`
D. `"450 ml, 525 g, 46 min"`

Answer

To solve the question, we need to find the specified fractions of a liter, a kilogram, and an hour step by step.

### Step 1: Find `12/25` of a liter

1. **Understand the total volume**: We know that 1 liter = 1000 milliliters (ml).
2. **Calculate `12/25` of 1000 ml**:
\[ \text{Volume} = \frac{12}{25} \times 1000 \text{ ml} \]
3. **Perform the multiplication**:
\[ \frac{12 \times 1000}{25} = \frac{12000}{25} = 480 \text{ ml} \]

### Step 2: Find `5/8` of a kilogram

1. **Understand the total weight**: We know that 1 kilogram = 1000 grams (g).
2. **Calculate `5/8` of 1000 g**:
\[ \text{Weight} = \frac{5}{8} \times 1000 \text{ g} \]
3. **Perform the multiplication**:
\[ \frac{5 \times 1000}{8} = \frac{5000}{8} = 625 \text{ g} \]

### Step 3: Find `3/5` of an hour

1. **Understand the total time**: We know that 1 hour = 60 minutes.
2. **Calculate `3/5` of 60 minutes**:
\[ \text{Time} = \frac{3}{5} \times 60 \text{ minutes} \]
3. **Perform the multiplication**:
\[ \frac{3 \times 60}{5} = \frac{180}{5} = 36 \text{ minutes} \]

### Final Answers:
(i) `12/25` of a liter = 480 ml
(ii) `5/8` of a kilogram = 625 g
(iii) `3/5` of an hour = 36 minutes
