First, you have to make the denominators the same. 7 4 --- - --- 12 12 Then, you subtract. 7 4 3 1 --- - --- = --- = --- 12 12 12 4
7/12 minus 1/3 = 1/4
(10/12) - (1/4) = (10/12) - (3/12) = 7/12
1/4 + 1/3 = 3/12 + 4/12 (12 is the least common multiple of 3 and 4) = 7/12
(-7/12) / (-3/4) = (7/12) / (3/4) = (7/12) * (4/3) = (7/3)*(1/3) = 7/9
-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.
7/12 − 1/4 = 16/48 which reduces to 1/3
1/3 + 1/4? 1/3 can be changed to 4/12.. 1/4 can be changed to 3/12.. 3/12 + 4/12 = 7/12 you can't simplify 7/12, so your final answer is 7/12.
First, you have to make the denominators the same. 7 4 --- - --- 12 12 Then, you subtract. 7 4 3 1 --- - --- = --- = --- 12 12 12 4
1/3 + 1/4 = 4/12 + 3/12 = 7/12
4/7 ÷ 12 = 1/21
change 1/4 to twelfths = 3/12. Now you can subtract: 7/12 - 3/12 = 4/12, which simplifies to 1/3.
7/12 minus 1/3 = 1/4
(10/12) - (1/4) = (10/12) - (3/12) = 7/12
1/4 + 1/3 = 3/12 + 4/12 (12 is the least common multiple of 3 and 4) = 7/12
(-7/12) / (-3/4) = (7/12) / (3/4) = (7/12) * (4/3) = (7/3)*(1/3) = 7/9
7/12 + 8/12 = 15/12 = 1 and 3/12 = 1 and 1/4
