Algebra.Com's Answer #77241 by BurningFlame_marc(77)![]() ![]() You can put this solution on YOUR website! Hello!\r \n" ); document.write( "\n" ); document.write( "No, you will only get the reciprocal(turning around of a fraction) if it's division.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For your question, I have a short way of solving it.\r \n" ); document.write( "\n" ); document.write( "Normally, people will multiply 5 by 14 then multiply 21 by 25 then simplify. \n" ); document.write( "If you do that you will get 70/525 then you still have to simplify this so your final answer will be 2/15. It's very long isn't it?\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "My solution will be, I will use cancelation. First find one numerator and one denominator that can be divided by a number. For this I found 2 pairs. 21 and 14,5 and 25. Then divide 14 and 21 by 7. The result is 2 and 3. Then divide 5 and 25 by 5. The result is 1 and 5. With that the new fractions are 1/3 and 2/5. \n" ); document.write( "Now, just multiply and you will get 2/15 which is the same as our first answer.\r \n" ); document.write( "\n" ); document.write( "The Final Answer is 2/15.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope you understand my solution! \n" ); document.write( " |
