Read the line graph carefully and answer the following question.

Find the ratio of items repaired in the month of March to the month of April.
The line graph shows the number of electrical items repaired in given month.

To find the ratio of electrical items repaired in the month of March to the month of April, we can extract the data points directly from the provided line graph:

- In the month of March, the number of items repaired (indicated by the data point on the line corresponding to the "March" label on the horizontal axis) is 25.
- In the month of April, the number of items repaired (indicated by the data point on the line corresponding to the "April" label on the horizontal axis) is 35.

Now, we calculate the ratio of the number of items repaired in March to those repaired in April:

$\text{Ratio}=\frac{\text{Items repaired in March}}{\text{Items repaired in April}}$

Substituting the values from the graph into the formula, we get:

$\text{Ratio}=\frac{25}{35}$

By dividing both the numerator and the denominator by their greatest common divisor, which is 5, we can simplify the fraction:

$\frac{25}{35}=\frac{5}{7}$

Therefore, the simplified ratio of items repaired in March to April is 5:7.
