A bar graph is drawn to the scale 1 cm = 250 units. The length of the bar representing a quantity of 300 units is________

Answer

To find the length of the bar representing a quantity of 300 units on a bar graph where the scale is 1 cm = 250 units, we can follow these steps:

### Step 1: Understand the scale
The scale given is 1 cm = 250 units. This means that for every 1 cm on the bar graph, it represents 250 units of the quantity.

### Step 2: Set up the proportion
We need to find out how many centimeters correspond to 300 units. We can set up a proportion based on the scale:
\[ \text{Length in cm} = \frac{\text{Quantity in units}}{\text{Units per cm}} \]
Here, the quantity is 300 units, and the units per cm is 250 units.

### Step 3: Substitute the values into the formula
Substituting the values into the formula gives us:
\[ \text{Length in cm} = \frac{300 \text{ units}}{250 \text{ units/cm}} \]

### Step 4: Perform the division
Now, we perform the division:
\[ \text{Length in cm} = \frac{300}{250} = 1.2 \text{ cm} \]

### Step 5: Conclusion
Therefore, the length of the bar representing a quantity of 300 units is **1.2 cm**.
