Describe two ways you could evaluate 37% of the sum of 27 3/5 and 15.9. Tell which method you would use and why?
THANK YOU!
1. 27 3/5 + 15.9 = 27.6 + 15.9 = 43.5.
0.37 * 43.5 = 16.095
2. 27 3/5 + 15.9 = 27 3/5 + 15 9/10 =
27+6/10 + 15+9/10 = 42 + 15/10 = 42+1.5
= 43.5.
0.37 * 43.5 = 16.095
The first method is shorter and easier;
I didn't have to deal with fractions.

To evaluate 37% of the sum of 27 3/5 and 15.9, there are two methods you can use:
1. Method 1: Use the decimal representation of the percentage.
- Convert 37% into a decimal by dividing it by 100: 37/100 = 0.37.
- Calculate the sum of 27 3/5 and 15.9: 27 3/5 + 15.9 = 27.6 + 15.9 = 43.5.
- Multiply the sum by the decimal representation of the percentage: 43.5 * 0.37 = 16.095.
2. Method 2: Use the fraction representation of the percentage.
- Convert 37% into a fraction by placing it over 100: 37/100.
- Calculate the sum of 27 3/5 and 15.9: 27 3/5 + 15.9 = 43.5.
- Multiply the sum by the fraction representation of the percentage: 43.5 * (37/100) = 16.095.
Both methods will give you the same result, which is 16.095.
Personally, I would use Method 1, which involves converting the percentage into a decimal. It is typically easier and more straightforward to perform calculations with decimals compared to fractions. However, if you are more comfortable with working with fractions, you can choose Method 2. The choice between the two methods ultimately depends on your preference and comfort level with decimals or fractions.
