Melanie was asked by her teacher to draw a figure divided into 100 equal parts and shade two-tenths of it. How many parts will she have to shade to show two-tenths

To find out how many parts Melanie will have to shade, we need to calculate two-tenths of 100.

Two-tenths of 100 can be calculated as 0.2 * 100 = <<0.2*100=20>>20.

So, Melanie will have to shade 20 parts to show two-tenths.
