How many `1/10` are there in `2/5` ?

Options

A. 4
B. 3
C. 8
D. 5

Answer

To find out how many \( \frac{1}{10} \) are there in \( \frac{2}{5} \), we can set up the equation as follows:

1. **Set Up the Equation**:
We want to find \( x \) such that:
\[ x \times \frac{1}{10} = \frac{2}{5} \]

2. **Multiply Both Sides by 10**:
To isolate \( x \), we can multiply both sides of the equation by 10:
\[ x = \frac{2}{5} \times 10 \]

3. **Perform the Multiplication**:
Now, we can simplify the right-hand side:
\[ x = \frac{2 \times 10}{5} = \frac{20}{5} \]

4. **Simplify the Fraction**:
Now, simplify \( \frac{20}{5} \):
\[ x = 4 \]

Thus, there are **4** \( \frac{1}{10} \) in \( \frac{2}{5} \).
