Question

A number line going from negative 2 to positive 2.

First, write the fractions as decimals.

Three-fourths is
and
1 and one-half is
.
Next, plot the numbers on the number line.

The least number is
.
The greatest number is
.
The correct order from least to greatest is
.

Answer 1

First, let's convert the fractions to decimals:

• Three-fourths (3/4) is equal to 0.75.
• One and one-half (1 1/2) is equal to 1.5.

Now, we can list all the numbers with their decimal values:

• 1.1 (already a decimal)
• Three-fourths (0.75)
• Negative 0.9 (already a decimal)
• Negative 1 (already a decimal)
• One and one-half (1.5)

Now let's compare all the values:

• Negative 1 = -1.0
• Negative 0.9 = -0.9
• Three-fourths = 0.75
• 1.1 = 1.1
• One and one-half = 1.5

Next, we can order these numbers from least to greatest:

• The least number is -1 (negative 1).
• The greatest number is 1.5 (one and one-half).

So, the correct order from least to greatest is:

• -1, -0.9, 0.75, 1.1, 1.5.

In summary:

1. Three-fourths is 0.75.
2. One and one-half is 1.5.
3. The least number is -1.
4. The greatest number is 1.5.
5. The correct order from least to greatest is -1, -0.9, 0.75, 1.1, 1.5.
