• 1/3 means the circle is divided into 3 equal slices and one of them is shaded.
• 1 and 3 share no common factor bigger than 1, so 1/3 is already in its simplest form.
• To turn 1/3 into a decimal, divide the top by the bottom: 1 ÷ 3 is about 0.333. Multiply that by 100 for the percentage, about 33.3%.
• The unshaded part is 2/3, because 1/3 and 2/3 add up to one whole.
