B) A common fraction
Step-by-step explanation:
<u>1 step.</u> Write down 0.4 divided by 1:
<u>2 step.</u> Multiply both top and bottom by 10 (because there are 1 digit after the decimal point):
This fraction is called a decimal fraction.

Answer:
Step-by-step explanation:
<em>The options are not given; however, the question can still be answered.</em>
Given
Direct Proportion:
In 20 minutes, y = 250 bottles
Required
Determine the graph
<em>In the first 20 minutes, y = 250</em>
<em>In the next 20 minutes, y = 250 + 250 = 500</em>
<em>In the next 20 minutes, y = 500 + 250 = 750</em>
<em />
This gives a arithmetic sequence:
250, 500, 750, ........
Next, is to determine the equation of the sequence using;
In this case;
Substitute these values in the above formula;
