Express the Value: Finding the Equivalent of 1.2

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

• Step 1: Identify the whole number part and the decimal part of $1.2$.
• Step 2: Convert the decimal part $0.2$ into a fraction.
• Step 3: Combine the whole number and the fraction into a mixed number.

Now, let's work through each step:
Step 1: The whole number part is $1$, and the decimal part is $0.2$.
Step 2: Since $0.2 = \frac{2}{10}$, we convert the decimal into the fraction $\frac{2}{10}$.
Step 3: Combining these, we have the mixed number $1\frac{2}{10}$.

Therefore, the solution to converting $1.2$ is $1\frac{2}{10}$, which corresponds to option 3.
