Answer 2

It seems like you've provided a set of equations with some missing values represented by letters. You've also included some fractions. Let me break down what you've provided:

1. Equation 1: B = 6.5 = 130 / 65 This equation shows that B is equal to both 6.5 and the fraction 130/65, which simplifies to 2. So, B is 6.5 or 2.

2. Equation 2: 46.2 / c = 0.462 / 0.0007 This equation relates the values 46.2 and c to two fractions. To solve for c, you can cross-multiply: 46.2 * 0.0007 = 0.462 * c 0.03234 = 0.462c c = 0.03234 / 0.462 c ≈ 0.070

3. Equation 3: ? = 0.462 / 0.0007 In this equation, you've used a question mark to represent an unknown value. The result of the division is approximately 660.

So, to summarize:

• B could be either 6.5 or 2.
• The value of c is approximately 0.070.
• The result of the third equation is approximately 660.
