Ratio And Proportion

From the proportion, we have: By cross-multiplying: Thus, the correct answer is .

Using the property of proportionality: Cross-multiply to find: Thus, the correct answer is 75.

We are given that: To find , we need to make the value of in both ratios the same. The least common multiple (LCM) of 4 and 8 is 8. So, we multiply the first ratio by 2: Now, we can combine the ratios: Thus, the correct answer is .

We are given that of of , which means: Dividing both sides by 0.05: This simplifies to: Thus, the correct answer is .
