Write a proportion to represent the problem:

A streaming channel had 1 million subscribers. The number of subscribers increased by 325% in May. How many subscribers are there now (in May)?

• $\frac{a}{1,000,000}=\frac{425}{100}$

• $\frac{a}{1,000,000}=\frac{325}{100}$

• $\frac{a}{1,000,000}=\frac{58.5}{100}$

• $\frac{a}{1,000,000}=\frac{326}{100}$

Write a proportion to represent the problem:
