what goes into 501 for a math question?

501/3=167\n\n167 is a prime number\n\nIs this what you were looing for?  If not, repost with more details.

98 is correct because 50/25=2. 49*2=98\n\ntry setting up a proportion: \n\n25   50\n----   ----\n49    n\n\nit may help!!

Alright. i=1-5,because the number on the bottom is the first number you will put in the expresion, and the number on top is the last number.and you put all the number inbetween in the expression too. So i will equal 1, 2, 3, 4, 5. Plug each one into the expression next to E. Now you have 5 answers. Sigma means something like "add" so you add all 5 answers together, and that is the final answer.

First do a prime factorization:\n250 / 2 = 125\n125 / 5 = 25\n25 / 5 = 5\n5 / 5 = 1\n\nSo 250 = 2 x 5 x 5 x 5\n\nNow do all the combinations:\n1 = 1\n2 = 2\n5 = 5\n2 x 5 = 10\n5 x 5 = 25\n2 x 5 x 5 = 50\n5 x 5 x 5 = 125\n2 x 5 x 5 x 5 = 250\n\nSo the positive factors of 250 are:\n1, 2, 5, 10, 25, 50, 125, 250\n\n(Note: Technically -1, -2, -5, -10, -25, -50, -125 and -250 are factors too but I assume they only want positive factors.)

Change them to improper fractions\n1 1/4 = 5/4\n6 2/3 = 20/3\n5/4 divided by 20/3 equals 5/4 times 3/20\n(5/4)(3/20) = 15/80 = 3/16\n\n20 divided by 6 2/3 = 20 divided by 20/3 = \n20 times 3/20 = (20/1)(3/20) = 60/20 = 3\n\n4/5 divided by 4/5 is 1.\n(Any nonzero number divide by itself is always 1.)\n\n16 1/2 divided by 6 2/3 = 33/2 divided by 20/3 = \n33/2 times 3/20 = (33/2)(3/20) = 99/40\n\n28 divided by 4/5 = (28/1)(5/4) = 35

1{p+5}/u-6\n\nThe 1 can be distributed into the {p+5}\n\n{p+5}/u-6

545+5=550 \n\nadding a small line to the first plus sign (making it a 4) allows this to become a true equation

20\n\none half of what 50 is 10 less than = 60/2 = 30\n\n20 is 10 more than 10, and 10 less than 30

you can further divide by 55 so (-540/5)/(1155/5)= -36/77\nand that's as low as you can go\nRival

for the first type of problem--60% of ? =45, you take 60% (which is the same as .6) and make the ? an x.  Of always means multiply, so it becomes .6x=45.  simply divide both sides by .6 and x=75. \n\nFor the second type--what % of 90 is 63, you just set it up the same way.  90X=45.  divide by 90 and you get .5 or 50%\n\nThe final type--39% of 1500, you simply multiply .39 by 1500 to get 585\n\nNow that you know how to do each type of problem, simply plug the right numbers into the equations and finish your homework.  Good luck.

It should be between .77 and .78.  You can decide how to round---up or down depending on your teacher's instructions.

its actually really simple to figure out 15%.  10% of 520 is obviously 52 (just move the decimal over one place, thereby removing the zero) and since u need 15%, you need 10%+ 5%, right?  so half of the 10% (52) is 5% which is 26.  Now add 52 and 26 and u get 78!   even if ur totally not a math person, dont get thrown off, any percent ending in a zero or 5 (10, 25, 50 etc) are really simple to do this way!

Just do the long division. So, for 20/21,\n21 goes into 200 9 times with a remainder of 11.\nThen 21 goes into 110 5 times with a remainder of 5.\nThen into 50 2 times with a remainder of 8.\nThen into 80 3 times with a remainder of 17.\nThen into 170 8 times with a remainder of 2.\nThen into 20 0 times witha remainder of 20,\nthen it repeats, so the decimal expansion is\n\n.952380952380952380.....

Those are the right numbers. As you suspected they have too many decimal places, however. To have them correct to 6 decimal places, look at the 7th decimal place. If this is 5 or more, round the 6th decimal up one, otherwise leave it the same and just drop all the numbers after it.\n\nSo for a) the answer would be 1.499975 and for b) it would be 1.499997.

31 / 5\n\nThat's because .2 is 1 / 5, so I just converted the 6 to 30 / 5 and added one more.
