Since there is no triangle and none of it is shaded, the answer is 0/0 which is an undefined quantity.
It is called the shaded part!
2/3 is not shaded.
It is 0.
Oh, dude, if part of the fraction isn't shaded, then that means it's not included in the value of the fraction. It's like having a pizza and only eating half of it - the other half is just there, chilling, not affecting the part you actually consumed. So yeah, if it's not shaded, it's basically like it doesn't exist in the fraction world.
1/2
The shaded parts
I see no shaded part fo the fraction must be "none".
There is no shaded space (indeed, no triangle) so the answer must be 0.
To write the number of shaded parts, you count the total number of shaded parts in the figure. To express the fraction of the whole that is shaded, you write the number of shaded parts over the total number of equal parts that make up the whole figure. For example, if there are 3 shaded parts out of a total of 8 equal parts, you would write this as "3/8."
3/10 are shaded.
5/8 of it.
It is called the shaded part!
0. Since there is no shaded part visible.
4 and a half
2/3 is not shaded.
2
None, since there is no shaded part of any figure!
