5/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/21
9, 11, 13, 15, 17, 19, 21
45/21 = 15/7
If: 7x+11y+13z = 15 Then: 7(15/21)+11(15/33)+13(15/39) = 15 because 5+5+5 =15 So it follows: 7(15/21)*11(15/33)*13(15/39) = 125 because 5*5*5 = 125 Therefore: x = 15/21 y = 15/33 and z = 15/39 Or as: x = 5/7 y = 5/11 and z = 5/13
7 and 13/21 is equivalent to the fraction 154/21.
13 + 21 - 7 + 12 = 15
(4/6) / (7/13) = 2/3 * (13/7) = 26/21 or 15/21
5/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/215/7 - 5/21 = 15/21 - 5/21 = 10/21
13/7 of 21 is 39.

21 and 13. The pattern is t(n) = (-n4 + 10n3 - 23n2 + 38n - 12)/12
45/21 = 15/7
If: 7x+11y+13z = 15 Then: 7(15/21)+11(15/33)+13(15/39) = 15 because 5+5+5 =15 So it follows: 7(15/21)*11(15/33)*13(15/39) = 125 because 5*5*5 = 125 Therefore: x = 15/21 y = 15/33 and z = 15/39 Or as: x = 5/7 y = 5/11 and z = 5/13
The actual answer is 7/8.
15/21 in lower terms is 5/7.It is 5/7.
7 and 13/21 is equivalent to the fraction 154/21.
