Algebra.Com's Answer #334638 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 3/4 + 3/4 = 6/4 I do not understand how the top number can be larger than the bottom number. \n" ); document.write( "--- \n" ); document.write( "Think of the 3/4 as a pie that has 4 equal parts. \n" ); document.write( "3/4 means you have three of the 4 \n" ); document.write( "--- \n" ); document.write( "So (3/4) + (3/4) means you have 3 of the 4 pieces from \n" ); document.write( "a first pie and you have 3 of the 4 pieces from a second \n" ); document.write( "pie. \n" ); document.write( "So you have 6 of those (1/4) pieces . \n" ); document.write( "Thus (3/4) + (3/4) = 6/4 \n" ); document.write( "------- \n" ); document.write( "The rule is, \" if you have the same denominators in fractions \n" ); document.write( "you are adding, you should just add the numerators and write \n" ); document.write( "that number over the denominator\". \n" ); document.write( "So (1/8) + (5/8) = 6/8 \n" ); document.write( "Or (2/3) + (3/3) = 5/3 \n" ); document.write( "===========================\r \n" ); document.write( "\n" ); document.write( " I also do not understand how to add fractions that have different bottom numbers. \n" ); document.write( "If the denominators are different you have to find a number called \n" ); document.write( "the least common denominator. \n" ); document.write( "--- \n" ); document.write( "So to add (2/3) + (1/5) you have to change (2/3) and you have to \n" ); document.write( "change (1/5) so they have the same denominator. \n" ); document.write( "---; \n" ); document.write( "How? \n" ); document.write( "(2/3) = (2/3)(5/5) = 10/15 \n" ); document.write( "(1/5) = (1/5)(3/3) = 3/15 \n" ); document.write( "---- \n" ); document.write( "Now you can add because the denominators are the same: \n" ); document.write( "(2/3) + (1/5) = (10/15)+(3/15) = 13/15 \n" ); document.write( "============================================ \n" ); document.write( "You can find many, many sites online that will show you \n" ); document.write( "how to add, subtract, multiply, and divide fractions. \n" ); document.write( "Just use Google and search for \"adding fractions\", \n" ); document.write( "or \"multiplying fractions\", or any other math you wish \n" ); document.write( "to learn. \n" ); document.write( "================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================ \n" ); document.write( " |
