If there are 30 children in a class and 3 are absent what is the percentage of absent children and what is the percentage of children present
\n" ); document.write( "
If you want to do %'s as ratios, then you can think of it as:

\n" ); document.write( "part/total = %/100
\n" ); document.write( "In this case the part that is absent is 3 and the total is 30, so:\r
\n" ); document.write( "\n" ); document.write( "\"3%2F30=x%2F100\"
\n" ); document.write( "\"1%2F10=x%2F100\"
\n" ); document.write( "Multiply both sides by 100.
\n" ); document.write( "\"100%281%2F10%29=100x%2F100\"
\n" ); document.write( "\"100%2F10=x\"
\n" ); document.write( "\"10=x\"
\n" ); document.write( "The percent of students absent is 10%. That means that 100%-10%=90% were present.\r
\n" ); document.write( "\n" ); document.write( "However, if you want practice. The number of students present is 30-3=27. So the proportion you would need to solve is.
\n" ); document.write( "\"27%2F30=x%2F100\"
\n" ); document.write( "Reduce and multiply both sides by 100 to see if you get 90%.\r
\n" ); document.write( "\n" ); document.write( "Happy Calculating!!! Hope that helped.\r
