Final answer:
To find the value of P in the proportion 1.2:3.6 :: P:3, we cross-multiply and solve for P, resulting in a value of P equal to 1.
Step-by-step explanation:
The question asks us to find the value of P in the proportion 1.2:3.6 :: P:3. This is a question of solving a proportion, which is a statement that two ratios are equal. To find P, we will cross-multiply the given values and solve the resulting equation for P.
To solve 1.2:3.6 :: P:3, we have:
- 1.2 / 3.6 = P / 3
- Cross-multiplying gives us 1.2 * 3 = 3.6 * P
- 3.6P = 3.6
- Dividing both sides by 3.6 to isolate P gives us P = 1
Therefore, the value of P is 1.
