• Here the whole is a GROUP, not one shape: the denominator 5 is how many oranges there are altogether, and each single one of them is one fifth of the set. The numerator 2 is how many of them the fraction counts.
• 2 and 5 share no common factor bigger than 1, so 2/5 is already in its simplest form.
• To turn 2/5 into a decimal, divide the top by the bottom: 2 ÷ 5 = 0.4. Multiply that by 100 for the percentage, 40%.
• The rest of the set is 3/5, because 2/5 and 3/5 add up to one whole set.
• The same method works on any amount, not just 5 oranges: to find 2/5 of a number, divide it by 5 and then multiply by 2.
