document.write( "Question 1190259: 2/3 of the beads are red 1/4 are yellow and the rest are blue there are 42 more red beads then blue. How much beads are there in total? I know that the answer is 72. but the problem is I am told to solve it without using algebra. And I cannot find a way to solve it without using an unknown variable.

\n" ); document.write( "2/3 + 1/4 = 8/12 + 3/12 = 11/12\r
\n" ); document.write( "\n" ); document.write( "Therefore, 1/12 are blue\r
\n" ); document.write( "\n" ); document.write( "The difference in proportion of red to blue is
\n" ); document.write( "8/12 - 1/12 = 7/12 \r
\n" ); document.write( "\n" ); document.write( "So the number of beads is 42/(7/12) = 42*12 / 7 = 72\r

\n" ); document.write( "\n" ); document.write( "Personally, if a student is learning Algebra, I find these types of problems to be minimally helpful (it is an exercise to show how much harder problems are to solve without Algebra, but isn't that the premise for learning Algebra in the first place... that it is a powerful tool?). One doesn't need to build a house without the assistance of power tools to realize that power tools save a lot of time.\r
