use a calculator, or do it the old fashion way. first u divide 13 into 80 which euals 6 with a remainder of 2 then u bring the 9 down and 13 goes into 29 2 times. the answer in 62 with a remainder of 3or 62 3/13

Find every number between 101 and 999 that is divisible by 7 and then add them together.  Hmmm......like I really am going to do that.

You can put it as the last number, right after 2, because that would be the 13th number.\nOr it could be after the number 6. If you add all the numbers and divide by 13, you would get 6.

Start at the decimal point.  \n\nMoving LEFT, you have digits/units (0), tens (9), hundreds (8), thousands, ten-thousands, hundred-thousands, millions, ten millions, etc.\n\nMoving RIGHT from the decimal point, you first have tenths (no 'units'), then hundredths, then thousands, ten thousandths, and so on.\n\nGood luck!!

Take a=0.080808. I will assume that the last 08 digits are repeated. This process will work for decimal to fraction conversions\n\na=0.08080808 etc\n\nMultiply both sides by 100\n\n100a = 8.08080808 etc\n\nSubtract first from the second\n\n99a = 8\n\nTherefore a = 8/99 = 0.08080808 etc\n\nTry the other ones

DIVIDE IT BY 100 TIMES THAT BY 20 AND THEN ADD THAT ONTO 12,590

Hi\n\nYou start by trying to divide 13 by 60 (i.e. how many times does 60 go into 13?) The answer of course is - it doesn't. So you know your answer must be a decimal number. Next add a zero to the 13 making it 130. Now try again. How many times does 60 go into 130. The answer is two with 10 left over. So the start of your answer is 0.2; Next add a zero to your leftover 10 making 100. How many times does 60 go into 100? Answer is 1 with 40 left over. So your answer is now at 0.21; next add a zero to your leftover 40 making 400. How many times does 60 go into 400. Answer is 6 with 40 leftover. So your answer has now moved on to 0.216; next add a zero to your leftover 40........ Can you see the pattern?? You just keep doing this until you want to stop :-) In this particular case the 6 will keep re-occurring and so your answer will never end; it will become 0.2166666666666 going on forever. Rounded this makes 0.22. Finally, add on the 34 degrees to the decimal and you get 34.22.\n\nNow you see why Clive Sinclair invented the modern calculator.

Using Roman numerals!  Twelve would be\n\nXII\n\nIf you cut that in half using a horizontal line, the top half looks like VII, which is 7.

Five and seven\n\nBy giving one, it's four and eight (twice)\n\nBy givng one, it's six and six

Just add them up using the calculator:\n1000 + 5999 + 9888 = 16887\n\nOr if you don't have a calculator:\n*111\n---------\n**1000\n+5999\n+9888\n=====\n16887\n=====

Simply multiply\n9 * 8 * 7 * 6\nBecause the first number can be 1-9 but not zero and the second number can be 1-9 but one number has already been used and so on and so forth.\nHope it helps.

12 and 7/8ths\n\nconvert the 1/2 to 4/8, the 3/4 to 6/8, add the fractions to get 15/8 which is 1 and 7/8, then add the whole numbers

8 numbers can be placed  in 8! ways.\nExchange the three two's gives no new numbers, so divide by 3!\nExchange the two six's gives no new numbers, so divide by 2!\n8! / ( 3! x 2! ) = 1680\n\nTh

you don't even need a calculator.  You should be able to work that out on paper.  9 x 7 is what?  Remember the magic quality of 9, the answer is one less than the number you are multiplying by, and adds to nine, so one less than 7 is 6, plus three is nine, so 9 x 6 is 63.  Write down the 3, carry the 6.  3 times 7 is?  Of course, 21, plus the 6 you carried 27.  write 27 next to the 3 you already have, and it's...\n273

1398\n\nEasy way:\nRound 399 to 400 (+1)\nRound 999 to 1000 (+1)\nAdd 1000+400=\n1400\nSubtract the two you added.\n1398

Hi Dear Kasey ;\n\nfirst take a a common denominator so i choose " 18 " \n8/9+5/6 =\n[( 2 * 8 ) + ( 3 * 5 )] / 18 =\n(16 + 15) / 18 = \n31 / 18 = 1.72 { a bar over 2 }\n\nGood Luck Darling ♣

bring the a's to one side... u then get 9a = 27 ... divide and answer is a = 3
