• 4/10 means the bar is divided into 10 equal parts and four of them are shaded.
• 4 and 10 both divide by 2, so 4/10 simplifies to 2/5 — 4 ÷ 2 = 2 and 10 ÷ 2 = 5.
• To turn 4/10 into a decimal, divide the top by the bottom: 4 ÷ 10 = 0.4. Multiply that by 100 for the percentage, 40%.
• The unshaded part is 6/10, because 4/10 and 6/10 add up to one whole.
