(1 cent * x ) = doller?

Yes. A dollar is equal to 100 cents.

Let us assume the present conversion rate is Rs45 per dollar.\n1 dollar = 100 cents\n==> 100cents = 4500 paise\n==> 1cent = 45 paise

So where's that starting point?  Either we start (yesterday) with Mary having $785.63 we subtract $57. and $125. for 603.63.  Then we add $57.25 for a total of 660.88 (B) \nOR\nwe start we $785.63 (today) anb subtract $57. and $125 for $603.63 (C).  The $57.25 doesn't matter cause Mary did that yesterday....

There IS a solution:\n\n1x - .15x = 680\n\n.85x = 680\n\n.85x/.85 = 680/.85\n\nx = 800\n\nThere you go!!!

A quarter ( not a nickel ) and a nickel

the check was for $15.35\n\nthe method isn't beautiful, but whatever.  i got it.\nwhere x is the # of dollars the check was for, and y is the # of cents the check was for:\n2(x + y/100) = y + x/100 - 4.45\n2x + 2y/100 = y + x/100 - 4.45\n200x + 2y = 100y + x - 445\n199x - 98y = -445\n199x - 98y + 445 = 0 (mod 100)\n99x - 98y + 45 = 0 (mod 100)\n-x - 2y = -45 (mod 100)\n2y - x = 55 (mod 100)\n\nyou want y to be roughly (2x + 4) too.\n\nhey, how about y =35  --> x=15\n\n15.35*2 = 30.70\n35.15 - 4.45 = 30.70\n\nvoila!

1/4\n\n.25 means 25/100\nor 1/4 of 100\n\nLike it takes 4 quarters (25 cent pieces) to make a dollar (100)

Compare the ratios --- 1/32 is to 1 as 91/2 is to X\n\n(1/32)/(1) = (91/2)/(x)\n\nCross multiply\n\nx*(1/32) = (91/2)*1 or\nx/32 = 91/2\n\nCross multiply again\n\n2x = 91*32\n2x = 2,912\nx = 1,456 feet\n\n~~~~~~~~~\nEdit:\n\nThanks fxstb.  But since there is no space, I take it as ninety-one halves, not nine and a half.  Also, even if it were 9 and 1/2 there is no need to convert to decimals.  Improper fractions (19/2) will still work the same way. BTW, it's not really "cross-multiplying" after you convert to decimals, it's just plain solving :)

1.35 x 10th\n\nI probably typed it wrong.  1.35 times 10 to the 10th power.

I'd like to tell you a couple of tricks for getting ABOUT the right answer, which is often all you need, for instance when you're buying something and want to guard against a major cashier's error.\nMultiplying two numbers: Try to simplify the problem. Say it's 15 cans of something at 39 cents a can. Well 39 is pretty close to 40, so you get 15*40=$6.00. Or if you want it exactly, 15*40=$6.00 but subtract 15 cents because you added it when you simplified. $6.00 - $0.15 = $5.85. That's a lot easier than mentally multiplying 15 by 39.\nOften there seems to be no way to simplify the problem. Like 34 * $0.57. Well see what happens if you decrease one a little and increase the other by the same percentage. Say we take 34 down to 30, that's a little more than 10% less. Then what's a little more than 10% of 57? About 7. So we add 7 to 57, and we have 30 * $.64 = $19.20. The actual answer is $19.38. Again, not too bad. Or a 3-digit number: Try $3.79 * 18. OK, lets put $3.79 up to $4.00, about a 5% increase. Then take about 5% off 18 and it's 17. $4.00 * 17 = $68.00, compared to the exact answer of $68.22. \nHow about when you have a bunch of different items in the supermarket cart and you want the approximate total? Just keep track of the dollars and remember the cents as simple fractions of a dollar. So if you have these items: $1.39, $3.75, $2.19, $7.63, you say 1 & 1/3 plus 3 & 3/4 is 5 & a little; plus 2 & a little is 7 & 1/2; plus 7 & 1/2 is 15. The actual total is $14.96. Again, not too bad, although it won't always be this close. I hope you can use these. It gets easier with practice.

well... if you want them to approximate... \n\nPercent basically breaks down to "per 100"... cent meaing 100.\n\nSo, have them move the decimal place in both numbers to the point where you're getting a number close to 100.\n\nin this case 99.26 and 109.35\n\nApproximating 99 and 110 so it'd be something like 90-92%

0.01 is already decimal..\nif you want 0.01%, it should be 0.01/100=0.0001

where are you from! i don't understand your question but here it goes one dollar in the USA is $1.oo is that what you wanted?

$1.19 - 3 quarters, 4 nickels, 4 pennies\n\nThe people above me who have changed there answers are cheats and should be reported as such !

.5 + .5 + .25 + 1.25 = 2.5\n\nTwo and a half.\n\nI like it, very funny!

The answer is:  4.47, and that's all there is to it!\n\nOk Vanessa, all you have to do is pull up your calculator (Start>Accessories).\nI am not suggesting you don't work it out in your head first: it's just basic. Check the answer on the calc, or, if you get stuck....go back.... to POWERS OF HIGH HOLY ROOTISM   SQUARE YOU KNOW, 1x1+(2x2)+2+(10-5)/1=       Simple:\n1+4+2+5/1=12
