One and one fourth = 5/4.
5/4 plus 1/3 is impossible to do, so we must make common denominators. Multiply 5/4 by 3 and 1/3 by 4.
15/12 plus 4/12 = 19/12.
one sixteenth
1/4 plus 1/4 plus 1/3 is = 0.833333
nothing
one third
7/12
Yes.
One fourth is three twelfths. So one twelfth plus three twelfths is four twelfths, which is also one third.
Seven and one twelfth
The answer is 2/3 plus 1/4 = 11/12
Do you mean: 1/4+x-1/3 = 2/3+3+1/4 If so then: x = 4
Yes by 1/36
25/36 The correct answer is 2/3 rd's or 67%
