Write the list of rational numbers in order from least to greate \( -2.15, \frac{3}{10},-1.6,-1 \frac{4}{5}, 0.8 \)

To list the rational numbers in order from least to greatest, we need to compare them. Let's convert all the numbers to a common form, such as decimal form, to make the comparison easier. Given rational numbers: 1. \( -2.15 \) 2. \( \frac{3}{10} \) 3. \( -1.6 \) 4. \( -1 \frac{4}{5} \) 5. \( 0.8 \) Converting the mixed number to a decimal: \( -1 \frac{4}{5} = -1 + \frac{4}{5} = -1 + 0.8 = -1.8 \) Now, the rational numbers in decimal form are: 1. \( -2.15 \) 2. \( \frac{3}{10} = 0.3 \) 3. \( -1.6 \) 4. \( -1.8 \) 5. \( 0.8 \) Now, let's list them in order from least to greatest: \( -2.15, -1.8, -1.6, 0.3, 0.8 \)
