3/4+1/12=9/12+1/12=10/12=5/6
19 and 3/4
Assuming that "forth" is your attempt to spell fourths, the answer is eleven and two fifths.
2/3 plus 1/4 = 11/12
It is; 1/4 plus 2/3 = 11/12
The answer is 3/8 plus 1/4 = 5/8
Three-fourths is one-fourth plus one-fourth plus one-fourth.
6 and 1 forth
3/12 + 5/12 = 8/12 = 2/3
2/3 + 4/6 = 8/6 or 1&2/6
1/2 + 1/4 = 2/4 +1/4 = 3/4
You start with 3 to the 1st, which is 3. Then multiply it by 3, 3x3=9.(3 to the 2nd) 9x3=27 (3 to the 3rd) Then 27x3=81 (3 to the 4th) + 17 = 98.
