AleksAgata [21]

Answer:

Cesar will be doing  15 research reports during the school year.

Step-by-step explanation:

Given:

Number of research report completed = 3

Percentage of the report completed for school year = 20%

We need to find total number of research report completed during school year.

Solution:

Let the total number of research report completed during school year be 'x'.

Now we can say that;

Number of research report completed is equal to Percentage of the report completed for school year multiplied by total number of research report completed during school year and then divided by 100.

framing in equation form we get;

3=\frac{20}{100}\times x\\\\3=0.2x

Dividing both side by 0.2 we get;

\frac{3}{0.2}=\frac{0.2x}{0.2}\\\\x=15

Hence Cesar will be doing  15 research reports during the school year.
