Rohit ate `4/7` part of an apple and his sister Ritu ate the remaining part of it? Who ate more and by how much?

Answer

To solve the problem step by step, we will determine how much of the apple Ritu ate and then compare the amounts eaten by Rohit and Ritu.

### Step 1: Identify the part of the apple Rohit ate.
Rohit ate \( \frac{4}{7} \) of the apple.

### Step 2: Calculate the remaining part of the apple.
To find out how much Ritu ate, we need to subtract the part Rohit ate from the whole apple. The whole apple can be represented as \( 1 \) (or \( \frac{7}{7} \)).

\[ \text{Part eaten by Ritu} = 1 - \frac{4}{7} \]

### Step 3: Convert 1 into a fraction with the same denominator.
We convert \( 1 \) into a fraction with a denominator of \( 7 \):

\[ 1 = \frac{7}{7} \]

### Step 4: Perform the subtraction.
Now we can perform the subtraction:

\[ \text{Part eaten by Ritu} = \frac{7}{7} - \frac{4}{7} = \frac{7 - 4}{7} = \frac{3}{7} \]

### Step 5: Compare the parts eaten by Rohit and Ritu.
Now we compare the two fractions:

- Rohit ate \( \frac{4}{7} \)
- Ritu ate \( \frac{3}{7} \)

Since \( \frac{4}{7} > \frac{3}{7} \), Rohit ate more than Ritu.

### Step 6: Calculate how much more Rohit ate than Ritu.
To find out how much more Rohit ate than Ritu, we subtract the amount Ritu ate from the amount Rohit ate:

\[ \text{Difference} = \frac{4}{7} - \frac{3}{7} = \frac{4 - 3}{7} = \frac{1}{7} \]

### Conclusion:
Rohit ate more than Ritu by \( \frac{1}{7} \) of the apple.
