Two of the angles measure 30 and 45. Thus, third angle = 180 - (30+45) = 180 - 75 = 105
Let's see, one-third of 30 would be 30 divided by three, so two-thirds would be twice that answer...
2/6 and 10/30
10/30, 100/300
The third number could be: 3, 6, 15 or 30
One third of 90 is 30 90 divided by 3 is 30. So, one third of 90 is 30, because 30+30+30=90.

30
2/3 of 45 = 45*2/3 = 30
10 is a third of 30
A third of 30 is 10 (30 ÷ 3 = 10).
