Answer 1

1)31/60 x 59/100 x 30/31 x 25/59  = 1/8
2) 75/76 x 100x101 x 76/75 x 25/33 x 303/500 = 51005/11
3)8/21 x 7/8 - 8/21 x 1/5= 27/105
4)15 x (3/5 + 2/3) = 19
5)(8/35 + 4/5) x 5/8 = 9/14
6) 75/91 x 27/50 + 75/91 x 23/50=  75/91

Answer 2

1) To solve the expression 31/60 + x + 59/100 + x + 30/31 + x + 25/59, we can combine the like terms. Adding the coefficients of x, we get 1x + 1x + 1x = 3x. The expression simplifies to 3x + 31/60 + 59/100 + 30/31 + 25/59. To add the fractions, we need to find a common denominator. The least common multiple of 60, 100, 31, and 59 is 18,660. Converting each fraction to have a denominator of 18,660, we get (31 * 311) / (60 * 311) + (59 * 186) / (100 * 186) + (30 * 604) / (31 * 604) + (25 * 316) / (59 * 316). Simplifying each fraction, we have 311/18660 + 10974/18660 + 18120/18660 + 7900/18660. Adding the fractions, we get (311 + 10974 + 18120 + 7900) / 18660. The numerator simplifies to 37,305. Therefore, the expression simplifies to 3x + 37,305/18660.

2) For the expression 75/76 + x + 100x101 + x + 76/75 + x + 25/33 + x + 303/500, we can combine the like terms. Adding the coefficients of x, we get 1x + 1x + 1x + 1x = 4x. The expression simplifies to 4x + 75/76 + 100x101 + 76/75 + 25/33 + 303/500. To add the fractions, we need to find a common denominator. The least common multiple of 76, 75, 33, and 500 is 114,300. Converting each fraction to have a denominator of 114,300, we get (75 * 1500) / (76 * 1500) + (76 * 1524) / (75 * 1524) + (25 * 3472) / (33 * 3472) + (303 * 2292) / (500 * 2292). Simplifying each fraction, we have 112,500
