According to the scores on the last math test, 80%, or 20, of the students in the class received an A. Find the number of studenin the entire class.

Sagot :

80% is the same as 4/5, so 4/5 of the class= 20. That means that if there was a picture, 4 parts would be shaded, and 1 would not. 1/4 of 20 is 5, so 1 part= 5 people. 5 x 5 = 25. 25 is the answer. :)

Answer

Find out the number of student the entire class.

To prove

Formula

[tex]Percentage = \frac{Part\ value\times100}{Total\ value}[/tex]

As given

According to the scores on the last math test, 80%, or 20, of the students in the class received an A.

i.e

Percentage = 80 %

Part value = 20

put in the formula

[tex]80 = \frac{20\times100}{Total\ value}[/tex]

[tex]Total\ value = \frac{20\times100}{80}[/tex]

[tex]Total\ value = \frac{2000}{80}[/tex]

Total value = 25

Therefore the total number of student in the entire class be 25.
