21\n\n\nExplanation:\n\nIf you don't get this, just forget about it.\n\nThink like this! How many sevenths are in 87? \n609. So how many sevenths in 4 and 1/7? 29.\nHow many 29s are in 609? 21!\n\n\nI hope this helped!

10 - 7 = 3\n\ntherefore 3 x 4 (for the 1/4) = 12\n the number is 12

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 :)

32\n\n8 is a quarter (25%) of one "whole" number\n\n8 * 4 (quarter) equals 32

there is another explanation 41\n7-3 = 4, hence 5-4 = 1\ntherefore 41

The answer is 2x+7 with a remainder of 32

(0 -7)/(-9-4) = -7/-13 = m = 7/13\n0 = 7/13(-9) + b ----> b = -63/13 \n\ny = 7/13x - 63/13

34 + 7= 41\n41 / 4 = 10.25\n10.25 is your answer!

x/(x-8) + 7 = 8/(x-8)\nMultiply everything by (x-8)\nx + 7(x-8) = 8\nDistribute the 7\nx + 7x - 56 = 8\nCombine x and 7x\n8x - 56 = 8\nAdd 56 to each side\n8x = 64\nDivide both sides by 8.\nx = 8\n\nNote that x-8 cannot equal zero, but we just found x to be 8.\nThat means x-8 = 8-8 = 0\nThus, we have no solution.

If there is no remainder, then this is a *whole number without a* decimal.  Or you could say that the decimal portion was zero.\n\ne.g. 27/3 = 9.0\n4/1 = 4.0\n-28/7 = -4.0\n-2/-2 = 1.0\n18/-3 = -6.0\n\netc.

1/7 = 0.1428 = 14.28%\n(1 in seven has to be true)
