• 1/9 means the circle is divided into 9 equal slices and one of them is shaded.
• 1 and 9 share no common factor bigger than 1, so 1/9 is already in its simplest form.
• To turn 1/9 into a decimal, divide the top by the bottom: 1 ÷ 9 is about 0.111. Multiply that by 100 for the percentage, about 11.1%.
• The unshaded part is 8/9, because 1/9 and 8/9 add up to one whole.
