• 1/2 means the bar is divided into 2 equal parts and one of them is shaded.
• 1 and 2 share no common factor bigger than 1, so 1/2 is already in its simplest form.
• To turn 1/2 into a decimal, divide the top by the bottom: 1 ÷ 2 = 0.5. Multiply that by 100 for the percentage, 50%.
• The unshaded part is 1/2, because 1/2 and 1/2 add up to one whole.
