Convert Mixed Number: Express 1 2/5 as Decimal

To solve this problem, we'll follow these steps:

• Step 1: Convert the fraction part of the mixed number $\frac{2}{5}$ to a decimal.
• Step 2: Add this decimal to the whole number part.

Now, let's work through each step:
Step 1: Convert $\frac{2}{5}$ to an equivalent fraction with a denominator of 10. Multiply both the numerator and the denominator by 2:
$\frac{2 \times 2}{5 \times 2} = \frac{4}{10}$ This means $\frac{2}{5} = 0.4$.

Step 2: Add the decimal 0.4 to the whole number part 1:
$1 + 0.4 = 1.4$

Therefore, the solution to the problem is $1.4$.
