Start with given equation .

1. In the right side you have three terms, two of them include p, so you can rewrite right side as

Then the whole equation is

as in option B. This means that option B is true and option A is false (because left sides are the same, but right sides differ).

2. Now multiply the equation by 100:

this equation is exactly as equation in option C. This gives you that option C is true.

3. Now multiply the equation by 10:

this equation differs from the equation in option D (because left sides are the same, but right sides differ). This gives you that option D is false.

4. At last, subtract 4 from the equation :

this equation differs from the equation in option E (because left sides are the same, but right sides differ). This gives you that option E is false.

**Answer: **correct choices are B and C.
