2/3 = 0.6666666666666667 3/8= 0.375 ======================= (2/3) - (3/8) = 0.2916666666666667
2 3/4 + 3/8 = (2×4+3)/4 + 3/8 = 11/4 + 3/8 = (11×2)/(4×2) + 3/8 = 22/8 + 3/8 = (22+3)/8 = 25/8 = (3×8+1)/8 = 3 1/8
3 - 8 is already simplified.
Considering this is your question. 2(3-8)+3 The answer is -7.
8/3 or 2 and 2/3
0.375
2/3 = 0.6666666666666667 3/8= 0.375 ======================= (2/3) - (3/8) = 0.2916666666666667
2 3/4 + 3/8 = (2×4+3)/4 + 3/8 = 11/4 + 3/8 = (11×2)/(4×2) + 3/8 = 22/8 + 3/8 = (22+3)/8 = 25/8 = (3×8+1)/8 = 3 1/8
8^(2/3) 8^(1/3) = 2, 2^2 = 4 -> 8^(2/3) = 4
(8)^1/3 + (8)^1/3 + (8)^1/3 = 2+2+2 = 6.
8/3 or 2 and 2/3
-3 - (-8) - (-2) = -3 + 8 +2 = +7
Division by a number is the same as multiplication by its inverse. So, (3/8) / (2/3) = (3/8) * (2/3) = (3*2) / (8*3) = 2/8 (cancelling the threes) = 1/4
The sum of 8 and 2/3 is 8 2/3
(8)^1/3 + (8)^1/3 + (8)^1/3 = 2+2+2 = 6
(3/8) / (2/3) = 9/16 (3 / 8 / 2 / 3) = 3/48 3 / (8/2) / 3 = 9 / 4 It is assumed you meant the first, but realize that "divided by" and "over" are synonymous and there is no clear implication of where the parentheses are. It would be more clear to say three-eighths divided by two thirds or similar.
Well easy :) (8)^1/3 + (8)^1/3 + (8)^1/3 = 2+2+2 = 6 ^_^
