You can put this solution on YOUR website!
the factors i can think of are:
\n" ); document.write( "1,3,13,39
\n" ); document.write( "i can't think of any others.
\n" ); document.write( "don't think there are any.
\n" ); document.write( "-----
\n" ); document.write( "9/16 or 4/7.
\n" ); document.write( "by the calculator, 4/7 is larger.
\n" ); document.write( "to make the denominators the same, multiply 9/16 * (7/7).
\n" ); document.write( "then multiply 4/7 * (16/16).
\n" ); document.write( "9/16 becomes 9*7/16*7 becomes 63/(16*7)
\n" ); document.write( "4/7 becomes 4*16/16*7 becomes 64/(16*7)
\n" ); document.write( "since the denominators are the same, the numerators tell the story.
\n" ); document.write( "slight edge to 4/7 confirms what the calculator says.
\n" ); document.write( "-----
\n" ); document.write( "3 is 10 times larger than .3.
\n" ); document.write( "if you divide 3 by 10 you will get .3
\n" ); document.write( "if you divide 3 by 100 you will get .03
\n" ); document.write( "anything to the right of the decimal place is less than 1.
\n" ); document.write( "1 is less than 3.
\n" ); document.write( "not sure how else to explain it.
\n" ); document.write( "in the decimal system which is what we are using when we add and subtract and multiply or divide, each position in the display of the numer has a meaning which is that the position is multiplied by the power of 10.
\n" ); document.write( "anything to the left of the decimal place and the power of 10 is positive.
\n" ); document.write( "anything to the right of the decimal place and the power is negative.
\n" ); document.write( "10 to a negative power is the same as 1/10 to a positive power.
\n" ); document.write( "here's how it looks:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " the number is 1111111.11111
\n" ); document.write( " abcdefghijklm\r
\n" ); document.write( "\n" ); document.write( "the letters are for identification purposes.
\n" ); document.write( "h is the decimal point which is the dividing line between whole numbers and fractional parts of a whole number
\n" ); document.write( "going from the decimal point to the left, each position is 10 times as large as the position to its right.
\n" ); document.write( "g = 1 * 10^0 equals 1 * 1
\n" ); document.write( "f = 1 * 10^1 equals 1 * 10
\n" ); document.write( "e = 1 * 10^3 equals 1 * 1000
\n" ); document.write( "each time you go to the left the number is 10 times larger than the number to its right.
\n" ); document.write( "going from decimal point to the right, each position is 10 times smaller than the position to its left.
\n" ); document.write( "i = 1 * 10^-1 which is the same as 1 * 1/10^1 which equals 1 * .1 or 1/10
\n" ); document.write( "j = 1 * 10^-2 which is the same as 1 * 1/10^2 which equals 1 * .01 or 1/100
\n" ); document.write( "k = 1 * 10^-3 which is the same as 1 * 1/10^3 which equals 1 * .001 or 1/1000\r
\n" ); document.write( "
