why is 2 3/4 less than 2

The fraction \( 2 \frac{3}{4} \) (which is read as “two and three-fourths”) represents a value that is greater than 2. To understand this, let's break it down:

1. The whole number part is 2.
2. The fractional part is \( \frac{3}{4} \), which is equal to 0.75 as a decimal.

When you combine these two parts, \( 2 \frac{3}{4} = 2 + \frac{3}{4} = 2 + 0.75 = 2.75 \).

Since 2.75 is greater than 2, we can conclude that \( 2 \frac{3}{4} \) is actually greater than 2, not less than 2.

If you meant to compare \( 2 \frac{3}{4} \) with some other number, please clarify, and I can help with that!

why is it less

It seems there might be a misunderstanding or a miscommunication regarding the values being compared. To clarify:

• \( 2 \frac{3}{4} \) (two and three-quarters) is equal to \( 2.75 \) in decimal form.
• 2 is simply \( 2.00 \) in decimal form.

Comparing the two:

• \( 2.75 \) (or \( 2 \frac{3}{4} \)) is greater than \( 2 \).

So, \( 2 \frac{3}{4} \) is not less than 2; it is indeed greater than 2.

why is 2 x 3/4 less than 2

Let's evaluate the expression \(2 \times \frac{3}{4}\) and compare it to 2.

1. Calculate \(2 \times \frac{3}{4}\): \[ 2 \times \frac{3}{4} = \frac{2 \times 3}{4} = \frac{6}{4} = \frac{3}{2} = 1.5 \]

So, \(2 \times \frac{3}{4} = 1.5\).

2. Compare it to 2:
   • \(1.5\) is indeed less than \(2\).

Thus, \(2 \times \frac{3}{4}\) is less than 2 because \(1.5 < 2\).

what ratio is equal to 2:5

The ratio \( 2:5 \) can be expressed in several equivalent forms by scaling both parts of the ratio by the same factor. Here are some examples of ratios that are equal to \( 2:5 \):

1. Scaling by 2: \[ 2 \times 2 : 5 \times 2 = 4 : 10 \]

2. Scaling by 3: \[ 2 \times 3 : 5 \times 3 = 6 : 15 \]

3. Scaling by 4: \[ 2 \times 4 : 5 \times 4 = 8 : 20 \]

In general, any ratio of the form \( 2n : 5n \) where \( n \) is a non-zero number will be equal to \( 2:5 \).

You can also express the ratio as a fraction: \[ \frac{2}{5} \]

This fraction is also equivalent to the ratio \( 2:5 \).

which ratio is equivalent to the ratio 2 : 5

To find ratios that are equivalent to \(2:5\), you can multiply both parts of the ratio by the same non-zero number. Here are a few examples:

1. Multiply by 2: \[ 2 \times 2 : 5 \times 2 = 4:10 \]

2. Multiply by 3: \[ 2 \times 3 : 5 \times 3 = 6:15 \]

3. Multiply by 4: \[ 2 \times 4 : 5 \times 4 = 8:20 \]

4. Multiply by 5: \[ 2 \times 5 : 5 \times 5 = 10:25 \]

5. Multiply by 10: \[ 2 \times 10 : 5 \times 10 = 20:50 \]

In general, any ratio of the form \(2n : 5n\) (where \(n\) is a positive non-zero integer) will be equivalent to \(2:5\).

You can also represent this ratio as a fraction: \[ \frac{2}{5} \]

This fraction is equivalent to the ratio \(2:5\).

avery drops a rock from an elevation of 2 1/4 meter above the surface of a body of water the rock lands at an elevation of -2 1/2 meters which value represents the distance the rock falls in meters

To determine the distance the rock falls, we need to find the difference in elevation between the initial height from which the rock was dropped and the height at which it lands.

1. Initial height: \(2 \frac{1}{4}\) meters
2. Final height: \(-2 \frac{1}{2}\) meters

Step 1: Convert the mixed numbers to improper fractions

• \(2 \frac{1}{4} = \frac{9}{4}\) (because \(2 \times 4 + 1 = 9\))
• \(-2 \frac{1}{2} = -\frac{5}{2}\) (because \(-2 \times 2 - 1 = -5\))

Step 2: Find the distance fallen

The distance fallen can be calculated by finding the difference between the initial and final heights. To do this properly, you calculate the total distance as follows:

\[ \text{Distance} = \text{Initial height} - \text{Final height} = \frac{9}{4} - \left(-\frac{5}{2}\right) \]

This is the same as adding since subtracting a negative is equivalent to addition.

Step 3: Find a common denominator

The common denominator for \(4\) and \(2\) is \(4\). So we need to convert \(-\frac{5}{2}\) to have a denominator of \(4\):

\[ -\frac{5}{2} = -\frac{5 \times 2}{2 \times 2} = -\frac{10}{4} \]

Step 4: Add the two fractions

Now we can add:

\[ \text{Distance} = \frac{9}{4} + \frac{10}{4} = \frac{19}{4} \]

Step 5: Convert back to a mixed number (if needed)

To convert \(\frac{19}{4}\) back to a mixed number:

\[ \frac{19}{4} = 4 \frac{3}{4} \]

Thus, the distance the rock falls is \(4 \frac{3}{4}\) meters or \(4.75\) meters in decimal.
