To calculate $\frac{4}{10} + \frac{3}{100}$, follow these steps:

Step 1: Make the denominators the same

• The least common denominator (LCD) of 10 and 100 is 100.
• Rewrite $\frac{4}{10}$ with a denominator of 100: $\frac{4}{10} = \frac{40}{100}$

Step 2: Add the fractions

Now that both fractions have the same denominator, add them directly: $\frac{40}{100} + \frac{3}{100} = \frac{43}{100}$

Step 3: Simplify (if needed)

The fraction $\frac{43}{100}$ is already in its simplest form.

Final Answer:

$\frac{4}{10} + \frac{3}{100} = \frac{43}{100} \text{ or } 0.43$
