It is a sequence of 5 numbers.
The numbers could be the start of the sequence generated by the polynomial:
Un = (59n4 - 562n3 + 1657n2 - 1442n + 360)/24 for n = 1, 2, 3, ...
can 3+23+ 23+10+50=1150
17/5 x 19/10 = 323/50 or 6 and 23/50
15 and 50 / by 5 = 3 and 10 3/10
2.3 = 23/10 and reduces to: 2 3/10
-23/7 x 7/50 = -23/50
2 3/10 or 23/10
The decimal 0.0031 as a fraction would be 31/10000.
23 / 10 is equal to 2.3 or 2 3/10
0.3x - 0.2y = 4 (or you can multiply by 10 in order to work with whole numbers) 0.2x - 0.3y = 5/23 3x - 2y = 40 2x -3y = 50/23 2(3x) - 2(2y)= 2(40) -3(2x) - (-3)(3y) = (-3)(50/23) 6x - 4y = 80 -6x +9y = -150/23 6x - 6x - 4y + 9y = 80 - 150/23 5y = 1690/23 y = (1690/23)/(5) y = (1690/23)(1/5) y = 338/23 2x - 3y = 50/23 2(338/23) - 3y = 50/23 676/23 -3y = 50/23 -3y = -676/23 + 60/23 -3y = -616/23 y = (-616/23)/(-3) y = (-616/23)(-1/3) y = 616/69
10/3 * 5 = 5*10/3 = 50/3 50/3 is 16+2/3 and about 16.67
23 + 3 + 17 + 7 = 50
50 x 10-3 = 0.05
