Answer: that is shading 10/12 of the figure
Explanation:
Shading 5/6 of the figure means that 5 out of the 12 equal pieces would be colored or filled in. To visualize this, imagine the figure being divided into 12 equal slices, like a pizza. If 5 of those slices were to be filled in with color, they would represent 5/6 of the total figure.
