If the ratio between two numbers is 2:5, what is the percentage of the smaller number?

If the ratio between two numbers is \( 2:5 \), it means for every 2 parts of the smaller number, there are 5 parts of the larger number. 

To find the percentage of the smaller number in relation to the total, follow these steps:

1. The total number of parts is \( 2 + 5 = 7 \) parts.
2. The smaller number is 2 parts out of this total.
3. To find the percentage, use the formula:

\[
\text{Percentage of smaller number} = \left(\frac{2}{7}\right) \times 100 = 28.57\%
\]

So, the smaller number is **28.57%** of the total.

Here are 5 related questions:
1. How do you calculate the percentage of the larger number in this scenario?
2. If the sum of the two numbers is 70, what are the actual values of the two numbers?
3. How do you express a ratio as a decimal?
4. Can you change this ratio into a fraction?
5. What happens if you increase both numbers by the same constant value—will the ratio remain the same?

**Tip:** When dealing with ratios, always think of them as a way to compare parts of a whole, which helps in converting them to percentages easily.

Learn how to calculate the percentage of the smaller number from a 2:5 ratio. The solution involves understanding the concept of ratios and percentages, using the formula (part/whole) * 100. Suitable for students in Grades 5-7.
