Add 8/15+4/15
12/15
2/4+1/2
Convert 12 to denominator 4: 1/2=2/4.
Now: 2/4+2/4=4/4=1.
2/6−1/3
Convert 1/3 to denominator 6: 1/3=2/6.
Now: 2/6−2/6=0.
5/6+1/3
Convert 1/3 to denominator 6: 1/3=2/6.
Now: 5/6+2/6=7/6.
Simplify: 7/6=1whole and 1/6.
7/12−1/6
Convert 1/6 to denominator 12: 1/6=2/12.
Now: 7/12−2/12=5/12.
