The problem r/84 = 32.5/182 is a proportion that can be solved by cross-multiplication. After calculating (84 × 32.5) and dividing the result by 182, we find that r equals 15.
To solve the equation r/84 = 32.5/182, we need to find the value of r. This is a proportion problem where two ratios are equal. We can solve it by using cross-multiplication.
- Multiply each side of the equation by the denominators, in this case, 84 and 182. It will look like this: r × 182 = 84 × 32.5.
- Do the multiplication on the right side: 84 × 32.5 = 2730.
- Now divide both sides by 182 to solve for r: 2730 / 182 = r.
- After the calculation, we find that r = 15.
Therefore, the value of r in the original proportion is 15.
