• 1/5 means the circle is divided into 5 equal slices and one of them is shaded.
• 1 and 5 share no common factor bigger than 1, so 1/5 is already in its simplest form.
• To turn 1/5 into a decimal, divide the top by the bottom: 1 ÷ 5 = 0.2. Multiply that by 100 for the percentage, 20%.
• The unshaded part is 4/5, because 1/5 and 4/5 add up to one whole.
