(-18-23+20)/3= (-21)/3=-7
6+8+7= 21 21/3 = 7 The average is 7.
21/60 = 7/20
Average = 20
7 + f - 21 = -20 Therefore, 7 + f = 1 f = 1 - 7 f = -6
(-18-23+20)/3= (-21)/3=-7
6+8+7= 21 21/3 = 7 The average is 7.
21/60 = 7/20
19 + 24 + 20 = 63/3 = 21 The average of the three numbers is 21.
What is 6 / 20 * 7 / 14 * 12 / 21 equals
-7/-8 x -20/-21 = 5/6
Average = 20
7 + f - 21 = -20 Therefore, 7 + f = 1 f = 1 - 7 f = -6
(20/21)/(2/3) = (20/21) x (3/2) = 10/7 = 1 and 3/7 = 1.428571429
20
21/60 or 7/20
21/60 = 7/20
