3. \( \frac{4}{5} \times 10= \)

To solve \( \frac{4}{5} \times 10 \), you can think of 10 as \( \frac{10}{1} \). When multiplying fractions, you multiply the numerators together and the denominators together. So, \( \frac{4 \times 10}{5 \times 1} = \frac{40}{5} \). When you simplify \( \frac{40}{5} \), you get 8. Thus, \( \frac{4}{5} \times 10 = 8 \). Now, here's a fun little tidbit: in real life, understanding fractions can help you whip up the perfect recipe! If a recipe calls for 10 cups of water and you only want to make \( \frac{4}{5} \) of it, knowing how to multiply fractions will ensure you get just the right amount—8 cups of water, no more, no less! And speaking of precision, one common mistake is forgetting to convert whole numbers into fractions first, which can lead to incorrect calculations. Just remember, fractions and whole numbers can play together—just give them a little boost by turning the whole number into a fraction!
