Divide 20 by 5/2.  If you have trouble dividing by fractions, try this:  Multiplying 20 x 2 (the denominator of the fraction) = 40, and then dividing 40 by 5 (the numerator of the fraction), or 40/5 = 8.\n\nIn general, if you want to know how many A/B there are in C, the answer is (CxB)/A.  In your example, A=5, B=2, C=20, so the answer is (20x2)/5 = 40/5 = 8.

you do 20/82 which is equal to 10/41. you multiply the numerator by 100 and get 1000/41. It equals to 24 and 16/41 percent. Remember if you want to get a percentage. simplify it. then multiply the numerator by 100. then you divide the numerator by the denominator

3.95e+20 is a notation which represents 3.95 times 10 to the 20th.  In other words, simply move the decimal place 20 times to the right and you get: 395,000,000,000,000,000,000.

Each zero at the end requires a 5 and a 2 somewhere in the factors.  Since there are more twos than 5s, all you need to do is count the number of 5s.  That's still an awfully big task.  Each number that is divisible by 5 has at least one 5 as a factor (e.g., 5, 10, 15...)  Of course there are 2000/5 = 400 of these.\n\nEach number divisible by 25 has at least 2 factors of 5.  There are 2000/25 of these or 80.  We already accounted for one of these 5s in the first count so this adds 80 more.\n\nEach number divisible by 5^3 (125) add another factor of 5 for 2000/125 = 16.\n\nNow, on to 5^4 this time the division is uneven: 2000/625 = 3.2 This means there are 3 numbers below 2000 divisible by 5^4\n\nOnce we get to 5^5 = 3125, it is bigger than 2000 so there are no more factors of 5.\n\nAll in all this comes to:  400 + 80 + 16 + 3 = 499 zeros.\n\nYou also asked about 1000!.  Using the same approach:\n\n200 + 40 + 8 + 1 = 249 zeros

-/(1525) = -/(305*5) = -/(61*5*5) = 5-/(61)\n\nThat's a simple as you can make make.\n5 -/(61) ~ 39.051...

(3,261 + 5) + (20 X 10) + (220 X 5)\n(3,266) + (200) + (1,100) = 4,566

20(1+2+3.....250) = 20 x (1+250) x 250 / 2 = \n\n20 x 251 x 250 /2 = 627,500

5 * 5 - 10/2 + 200\n= 5 * 5 - 5 + 200\n= 25 - 5 + 200\n= 25 + 195\n= 220\n\nThe answer is 220

Here's your fraction:\n6 5/20\n\nYou should probably reduce the fraction to its lowest terms first, so 6 5/20 is the same as:\n6 1/4\n\nIf you divide 1/4 on your calculator, or using long division, you get 0.25.\n\nSo your final answer is 6.25\n\nYou can also convert it to an improper fraction and do it that way:\nNumerator = Denominator * 6 + 1 = 4 * 6 + 1 = 25\nDenominator = 4\n\n25/4 --> long division\n= 6.25\n\nFinally, one last way is to put it as a number over a power of 10 (10, 100, 1000, etc.)\n\nStart with 25/4.  If you multiply top and bottom by 25 you get:\n625/100.  Just move the decimal place 2 spaces to the left --> 6.25

I made an applet that solves any 24 problem, so I got the answer easily.\n5*(5-1/5)=24

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

20 is your base, but we think of % as out of 100, so\n20 * X = 100   X =5\n so also multiply 3 x 5 = 15\n\n15 %

You substitute 10 for a, and 20 for b, so you have 10^2 + 20^2 = c^2, then you do the math, so you have 500= c^2\n\nThen you square 500 so c=22.36

Thats funny.  Tell me another one.\n\nMaybe its like 5-2=2\n\n\nlol

20 - - 4 = 24\nminus and minus = plus\nie\n20 - - 4 = 20 + 4 = 24

Divide 19 by 42. You should get a decimal. Multiply this number by 100.\n\nYou can check your answer by estimating. Since 20 is about half of 40, 19 should be just under 50% of 42. (It's actually around 45%.)
