To simplify the expression \(2024 \times 30\% + 2024 \times \frac{7}{10}\), let's break it down step by step.

1. **Convert the percentage to a decimal**:
\[
30\% = \frac{30}{100} = 0.3
\]

2. **Rewrite the expression**:
The expression can be rewritten using decimals:
\[
2024 \times 0.3 + 2024 \times \frac{7}{10}
\]

3. **Factor out \(2024\)**:
\[
2024 \times (0.3 + \frac{7}{10})
\]

4. **Calculate \(\frac{7}{10}\)** in decimal:
\[
\frac{7}{10} = 0.7
\]

5. **Now add \(0.3\) and \(0.7\)**:
\[
0.3 + 0.7 = 1.0
\]

6. **Final expression**:
\[
2024 \times 1.0 = 2024
\]

Thus, the simplified form of the expression \(2024 \times 30\% + 2024 \times \frac{7}{10}\) is:

\[
\boxed{2024}
\]

For the second expression \(2024 \times 30\% + 2024 \times \frac{7}{10}\) (with no "b" included this time), the calculations remain the same, confirming the simplified result is also:

\[
\boxed{2024}
\]
