Sophie's friend gave her 1/2 of a chocolate bar. She ate 1/5 of it. How much did she eat?
To determine how much of the candy bar your friend ate, we need to subtract the amount you ate (1/5) from the amount your friend gave you (1/2).
To subtract fractions, the denominators (the bottom number) must be the same. In this case, the denominators are already the same (both are 5).
To subtract the two fractions, subtract the numerators (the top number) and keep the common denominator.
1/2 - 1/5 can be calculated as:
(1/2) - (1/5) = [(1 * 5) - (1 * 2)] / (2 * 5) = (5 - 2) / 10 = 3/10
Therefore, your friend ate 3/10 of the candy bar.
