1. Understand the meaning of percentages: Percentages represent a part of 100. So, 210% means 210 out of 100, which can also be written as 2.10 in decimal form.

2. Set up an equation: We need to find the number such that 210% of it equals 147. This can be expressed as:
[tex]\[
2.10 \times \text{number} = 147
\][/tex]

3. Solve for the unknown number: To find the number, divide both sides of the equation by 2.10:
[tex]\[
\text{number} = \frac{147}{2.10}
\][/tex]

4. Calculate the result:
[tex]\[
\text{number} = 70
\][/tex]

Therefore, 210% of 70 is 147.
