What 1/4 +1/9+1/2+4/5= what?

You have to find a common denominator before you can add them together by hand. In this case it is 180. Use this to convert the terms:\n1/4 = 45/180\n1/9 = 20/180\n1/2 = 90/180\n4/5 = 144/180\nNow that they have the same denominator, you can add them together:\n45/180 + 20/180 + 90/180 + 144/180 \n=299/180 or in decimal form: 1.66111\n\nPlease give me 10 points!

1/3 + 1/3 + 1/3 = 3/3, or 1 cup\n\n3/4 + 1/4 + 1/4 = 5/4, or 1 and 1/4 cups\n\n2/3 + 2/3 = 4/3, or 1 and 1/3 cups\n\n2/3 + 1/3 + 1/4, you have to get a common denominator, would be the same as 8/12 + 4/12 + 3/12 = 15/12, or 1 and 3/12 cups, or 1 and 1/4 cups\n\n3/4 + 3/4 = 6/4, or 1 and 2/4, or 1 and 1/2 cups******** this is your answer

Since y = 9 when x=4,\nthen y=9/2 when x=4/2=2\n\nNo calculations required.\n\nBut if you must, this is done by Solving for k when x=4 and y=9\n9=4k+8\n4k=9-8\nk=1/4\n\nUsing k and x=2, then, y= 1/4(2) +4\n                       y= 1/2+4 =9/2

1/2*1/4*1/10 = 1/80\n\n=> 1/80 of 800 = 800/80 = 10\n\none half of one quarter of one tenth of 800 is 10.

1/(1*2) = 1/2\n1/(1*2) + 1/(2*3) = 1/2 + 1/6 = 2/3\n1/(1*2) + .... + 1/(3*4) = 2/3 + 1/12 = 3/4\n\nA pattern is starting to appear eh??\n\nLets see:\n\n1/(1*2) + .... + 1/(4*5) = 3/4 + 1/20 = 4/5 Yesssssssssssss!!\n\nSo I suggest that 1/(1*2) + 1/(2*3) + ..... + 1/(99*100) = 99/100\n\n(See also Scott's formal proof above\n\nHe has based it on the fact that 1/[(n - 1)n] = 1/(n - 1) - 1/n\n\nie 1/4*5 = 1/4 - 1/5)

13/16 - 1/4 is like 13/16 - 4/16 which equal 9/16\n\nYou just have to get the denominators equal to add or subtract fractions...so just multiply the the top and bottom of 1/4 by 4 and you get 4/16 (which is the same as 1/4). It works the same for all fractions that you want to add or subtract.
