To solve this problem, you need to write equations using what you know. You know that the US population is 1/4 of China's population. This can be written as:
\n" ); document.write( "U = (1/4)*C (where U = US population, C = China population)
\n" ); document.write( "We also know that US has 300 million people:
\n" ); document.write( "U = 300,000,000
\n" ); document.write( "Now plug the value of U into the first equation and solve for C:
\n" ); document.write( "U = (1/4)C
\n" ); document.write( "300,000,000 = (1/4)C
\n" ); document.write( "300,000,000/(1/4) = ((1/4)C)/(1/4)
\n" ); document.write( "1,200,000,000 = C
\n" ); document.write( "So the population of China is 1,200,000,000 people. \n" ); document.write( "

\n" );
