which fraction is larger 1/3, 2/5, 8/15, 13/30. and how do i solve this
\n" ); document.write( "Whenever you are given numerical fractions and asked to find the largest,smallest etc. what is to be done is without changing the meaning bring them to a common denominator and then denominator being the same looking at the value of the nrs we can decide which is bigger than what fraction.
\n" ); document.write( "How to bring the drs to a common denominator. What we mean by a common denominator is that \"same denominator\"
\n" ); document.write( "Find the lcm of all the denominators of the given fractions convert every fraction to a fraction whose dr is this lcm value.
\n" ); document.write( "Now given 1/3, 2/5, 8/15, 13/30
\n" ); document.write( "the lcm of 3,5,15 and 30 is 30
\n" ); document.write( "and 3X(10)= 30, 5X(6) = 30, 15X(2) = 30
\n" ); document.write( "Therefore (1/3) = (1/3)X(10/10)=(10/30),
\n" ); document.write( "(2/5)= (2/5)X(6/6)=(12/30),
\n" ); document.write( "(8/15) = (8/15)X(2/2)=(16/30)
\n" ); document.write( "and therefore 1/3,2/5, 8/15, 13/30 become respectively
\n" ); document.write( "10/30,12/30,16/30 and 13/30
\n" ); document.write( "Now studying the nrs, 10,12,16,and 13, arranging them in ascending order (that is from smallest to the next bigger to the next bigger ... to the biggest)
\n" ); document.write( "We have 10,12,13 and 16
\n" ); document.write( "Therefore the fractions in the ascending order are 10/30,12/30,13/30 and 16/30
\n" ); document.write( "That is 1/3,2/5, 13/30 ,8/15
\n" ); document.write( "Therefore 1/3 < 2/5 < 13/30 < 8/15
\n" ); document.write( "(1/3) is the smallest
\n" ); document.write( "larger than (1/3) is (2/5)
\n" ); document.write( "larger than (2/5) is (13/30)
\n" ); document.write( "The largest is (8/15)
\n" ); document.write( "Note: make a neat copy of the above notes removing all explanatory text.That will be your answer for the test.\r
