what is the prime factorization of 200?
360690
200/2=100 so 200=2*100\n100/2=50  so 200=2*(2*50)\n50/2=25 so  200=(2*2*(2*25))\n25/5=5  so  200=2*2*2*5*5 \nand you cannot go furthermore\n200=\n2*2*2*5*5=\n2^3*5^2

Because 3 and 23 are prime, the number will be a multiple of (3 x 23) = 69.\n\nNext, the two digit number in the thousand and hundreds place must be *just before* the two digit number in my tens and ones place.\n\nThe answer is 2829.\n\nYou can confirm this by checking the list below:\n2001\n2070\n2139\n2208\n2277\n2346\n2415\n2484\n2553\n2622\n2691\n2760\n2829 <--\n2898\n2967\n3036\n3105\n3174\n3243\n3312\n3381\n3450\n3519\n3588\n3657\n3726\n3795\n3864\n3933\n4002\n4071\n4140\n4209\n4278\n4347\n4416\n4485\n4554\n4623\n4692\n4761\n4830\n4899\n4968\n5037\n5106\n5175\n5244\n5313\n5382\n5451\n5520\n5589\n5658\n5727\n5796\n5865\n5934\n6003\n6072\n6141\n6210\n6279\n6348\n6417\n6486\n6555\n6624\n6693\n6762\n6831\n6900\n6969\n7038\n7107\n7176\n7245\n7314\n7383\n7452\n7521\n7590\n7659\n7728\n7797\n7866\n7935\n8004\n8073\n8142\n8211\n8280\n8349\n8418\n8487\n8556\n8625\n8694\n8763\n8832\n8901\n8970\n9039\n9108\n9177\n9246\n9315\n9384\n9453\n9522\n9591\n9660\n9729\n9798\n9867\n9936

Sorry, 0.19 is not equal to 200..... ? Perhaps you mean fraction ratios? (0.19 / 200) = (0.16 / x ) If that is the case, cross multiply and divide (0.16 * 200) / 0.16 = 168.42

Reduce it untill the # on the bottom is prime.\n (divide the top AND bottom by 2 untill you get a decimal.)

The factors of 186 can be found as follows:\n\n186 is even, so 2 is a factor\n186/2 = 93\n\nBoth 9 and 3 are divisable by 3, so 3 is a factor\n93/3=31\n\n31 is prime, so it's the final factor.\n\nI'm not sure how you'll get anything to add up to 46 though, maybe 36?

67*18/6+17-18=200 is correct mathematically and it follows the order of precedence.\n\nOrder of Precedence can be easily remembered by the expression "Please Excuse My Dear Aunt Sally".  You follow (P)arenthesis, (E)xponents, (M)ultiplication, (D)ivision, (A)ddition, then (S)ubtraction.\n\nThere is no parenthesis or exponents in this problem.\n\n67*18/6+17-18=200\nMultiplication first: 1206/6+17-18\nDivision next: 201+17-18\nThen addition: 218-18\nSubtraction lastly: 200\n\nProblem solved!

Try to factorise number 319.\nIt is 11 * 29\nSo you have 11 rows 29 people per row \nor 29 rows with 11 people per row.\n\nIf you wonder how to find it it is simple\nTry to divide 319 with prime numbers\n\n2,3,5,7,11,13,17\n\nOnly 11 is ok!

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.)

It's almost 2/3, but not exactly.\n\nInstead 667/1000 is already in lowest terms.\n\nThe prime factors of 667 are 23 x 29\nThe prime factors of 1000 are 2 x 2 x 2 x 5 x 5 x 5.\n\nThey have none in common so you can't reduce it further.
