1/2 + 3/5 = 5/10 + 6/10 = 11/10 = 1 i 1/10
7 i 1/3 - 6 i 1/6 = 7 i 2/6 - 6 i 1/6 = 1 i 1/6
3/24 * 18 = 54/24 = 2 i 6/24 = 2 i 1/4
9/7 : 12 = 9/7 * 1/12 = 3/28

7 1/3 - 6 1/6 = 22/3 - 37/6= 44/6-37/6 = 7/6
3/24*18=
[tex] \frac{3 \times 18}{24} [/tex]
= 54/24= 2 6/24= 2 1/4
9/7:12= 9/7*1/12= 3/7 * 1/4 = 3/28
