3/4 of 12 = 12*3/4 = 9
2/3 + 3/4 = (2×4)/(3×4) + (3×3)/(4×3) = 8/12 + 9/12 = (8+9)/12 = 17/12 = (1×12+5)/12 = 1 5/12.
1/3 - 1/4 = (1×4)/(3×4) - (1×3)/(4×3) = 4/12 - 3/12 = (4-3)/12 = 1/12
9/12 = (3×3)/(4×3) = 3/4
3/4 + 2/3 = (3*3)/(4*3) + (2*4)/(3*4) = 9/12 + 8/12 = 17/12 or 1 and 5/12
12 is the LCM of any of the following 44 sets:{12},{1, 12}, {2, 12}, {3, 4}, {3, 12}, {4, 6} , {4, 12}, {6, 12},{1, 2, 12}, {1, 3, 4}, {1, 3, 12}, {1, 4, 6}, {1, 4, 12},{1, 6, 12}, {2, 3, 4}, {2, 3, 12}, {2, 4, 6}, {2, 4, 12},{2, 6, 12}, {3, 4, 6}, {3, 4, 12}, {3, 6, 12}, {4, 6, 12},{1, 2, 3, 12}, {1, 2, 4, 12}, {1, 2, 6, 12}, {1, 3, 4, 12},{1, 3, 6, 12}, {1, 4, 6, 12}, {1, 2, 4, 6}, {1, 3, 4, 6},{1, 2, 3, 4}, {2, 3, 4, 6}, {2, 3, 4, 12}, {2, 3, 6, 12},{2, 4, 6, 12}, {3, 4, 6, 12},{1, 2, 3, 4, 6}, {1, 2, 3, 4, 12}, {1, 2, 3, 6, 12},{1, 2, 4, 6, 12}, {1, 3, 4, 6, 12}, {2, 3, 4, 6, 12},{1, 2, 3, 4, 6, 12}.
3/4 x 3/3 = 9/12 1/3 x 4/4 = 4/12 9/12 - 4/12 = 5/12 Answer: 5 out of 12
3x4? Well, 3x4 is basically 3+3+3+3 or 4+4+4. 4+4+4=12 3+3+3+3=12 Basically, 3x4 equals to 12.
-3/4 + -7/12 = (-3×3)/(4×3) + -7/12 = -9/12 + -7/12 = (-9 + -7)/12 = -16/12 = (-4×4)/(3×4) = -4/3 = -1 1/3.
3
3/4 of 12 = 12*3/4 = 9
(3/4) x 12 = (3 x 12) /4 = 36/4 = 9
2/3 + 3/4 = (2×4)/(3×4) + (3×3)/(4×3) = 8/12 + 9/12 = (8+9)/12 = 17/12 = (1×12+5)/12 = 1 5/12.
1/3 - 1/4 = (1×4)/(3×4) - (1×3)/(4×3) = 4/12 - 3/12 = (4-3)/12 = 1/12
-16
3 x 4 = 12
The Lowest Common Multiple of 3 and 4 is 12. 3*4=12 4*3=12
