Given:
\n" ); document.write( ".
\n" ); document.write( "\"12+kg%2Fml\"
\n" ); document.write( ".
\n" ); document.write( "To convert this to \"gms%2Fltr\" we need to recall that:
\n" ); document.write( ".
\n" ); document.write( "1 kg = 1000 gms
\n" ); document.write( "and
\n" ); document.write( "1 ltr = 1000 mls
\n" ); document.write( ".
\n" ); document.write( "We are going to multiply the original amount we were give by two conversions, one conversion
\n" ); document.write( "that changes kg to gms and one that changes ml to ltrs. So we have to have our conversions
\n" ); document.write( "arranged so that the kg in the conversion will cancel the kg in the problem we were given
\n" ); document.write( "and the ml in the conversion will also cancel the ml in the problem we were given.
\n" ); document.write( ".
\n" ); document.write( "To cancel the kg in the given problem (which is in the numerator) we need a kg in the
\n" ); document.write( "denominator. So our conversion factor will have kg in the denominator and gms in the numerator.
\n" ); document.write( "So the weight conversion must be:
\n" ); document.write( ".
\n" ); document.write( "\"%28%281000+gms%29%2F%281kg%29%29\"
\n" ); document.write( ".
\n" ); document.write( "To cancel the ml in the given problem (which is in the denominator) we need a ml in the numerator.
\n" ); document.write( "So our conversion factor will have ml in the numerator and ltr in the denominator.
\n" ); document.write( "That means that this conversion factor for the liquid measure must be:
\n" ); document.write( ".
\n" ); document.write( "\"%28%281000mls%29%2F%281+ltr%29%29\"
\n" ); document.write( ".
\n" ); document.write( "Now all that we need to do is to multiply the original given by these two conversion
\n" ); document.write( "factors as follows:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "Notice how the weight units cancel:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "Next notice how the liquid measure units also cancel:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "Then notice that in the denominators we can ignore the \"1\" associated with the kg and with
\n" ); document.write( "the ltr.
\n" ); document.write( "As a result we are left with:
\n" ); document.write( ".
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "You can now see that the remaining units are gms in the numerator and ltr in the denominator,
\n" ); document.write( "just as the problem asked for. All you have to do is multiply the numbers that all appear
\n" ); document.write( "in the numerator
\n" ); document.write( "to get:
\n" ); document.write( ".
\n" ); document.write( "\"%2812%2A1000%2A1000%29gm%2Fltr+=+12000000+%28gm%2Fltr%29+\"
\n" ); document.write( ".
\n" ); document.write( "To shorten this you can write the answer in the form of exponential notation as:
\n" ); document.write( ".
\n" ); document.write( "\"12%2A10%5E%286%29+%28gm%2Fltr%29\"
\n" ); document.write( ".
\n" ); document.write( "or in scientific notation as:
\n" ); document.write( ".
\n" ); document.write( "\"1.2%2A10%5E%287%29+%28gm%2Fltr%29\"
\n" ); document.write( ".
\n" ); document.write( "Once you get the hang of this process, it will go much faster for you. In each of the conversion
\n" ); document.write( "factors you relate the equivalent amounts: 1 kg and 1000 gms, 1 ltr and 1000 ml, or any
\n" ); document.write( "other equivalent amounts that you may need ... 1 ton and 2000 lbs, 1 gallon and 4 quarts,
\n" ); document.write( "and so on. Then all you have to do is decide which part of the equivalence goes into the
\n" ); document.write( "numerator of your conversion factor and which goes into the denominator of the conversion factor.
\n" ); document.write( "That decision depends on how you need to place them to cancel the units in the given
\n" ); document.write( "problem. The more of these types of problems you do, the more logical the process
\n" ); document.write( "will become to you. And you will become aware that you may need to have more conversion
\n" ); document.write( "factors in the multiplication chain to work your way to the units you need in the solution.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to work your way through this problem and others like them.
