Given 3/4/8 + 1/3/4 From given expression, two cases can be considered: A: 3/(4/8) + 1/(3/4), or B: (3/4)/8 + (1/3)/4 The calculation for each of them is shown below:
A: 3/(4/8) + 1/(3/4) = 3x(8/4) + 1x(4/3) = (3x8)/4 + (1x4)/3 = 24/4 + 4/3 = 24x3/12 + 4x4/12*
= 72/12 + 16/12 = 88/12 = 2x2x2x11/2x2x3 = 22/3 (* the least common multiple of 4 and 3 is 12)
B: (3/4)/8 + (1/3)/4 = (3/4)x(1/8) + (1/3)x(1/4) = 3/(4x8) + 1/(3x4) = (3x3)/(4x8x3) + (1x8)/(3x4x8)
=9/96 + 8/96** = 17/96 (** LCM of 3,4,8 is 96)
Terefore,the answer is: 22/3 or 17/96
