14/21 = 2/3
The same way you reduce a normal fraction: 14/21 = 2/3, so 5 14/21 = 5 2/3.
Neither, Both fractions reduce to 3/7, so they are equal.
6x - 9 = 21 6x = 21 + 9 6x = 28 x = 28/6 Reduce to: x = 14/3
X+14=-21 X=-21-14 X=-35 is your answer.
-14/21 = -2/3
14/21 = 14÷7/21÷7 = 2/3
The LCM of 14 and 21 is 42.
You cannot reduce it further.
21:14 21/7:14/7 3:2
If that's -21 + 14, the answer is -7. If that's -21/14, the answer is -3/2 or -1 and 1/2
-21 + 14 = -7
14 * 21 = 294
