Hello,

For example I received an examination scored 77 and its equivalent in percentage is 90%. How to find it's 100% value?

For example it is something like 77 / 84 (just example)

Pls. sorry for bad explanation.:)

Simple method of three:
X=unknown percentage.
C=your current score
T=the best score for the specific test

X=C/T*100 (in %)

If you know your percentage in the test, and you know the percentage of the test in the total grade, then your contribution to your total grade is
X=final contribution
T=test contribution
S=your score in the test in percentage

X=T*S

Does that help?

Can you try to explain what you have and what you want a bit better? I don't understand what you want to achieve.

Um,

For example, the percentage is 75% and its value is 3.. So how to know the denominator of the 3? In this case, its 4...\[\frac{3}{4}=75%\]

MMMM, the denominator now is missing,,,<br><br>\[\frac{77}{?}=90%\]


plllllllllllllllllllllllls help....

\[0.9=\frac{77}{max score}\]

Divide 77 by .9
and about 85.5 (?!) points were available, if 77 points correct gave you 90%
