Find the product. \[ 0.25 \times 3.6 \]

To find the product of 0.25 and 3.6, you can first convert them into fractions. 0.25 can be written as \( \frac{1}{4} \) and 3.6 as \( \frac{36}{10} \) or \( \frac{18}{5} \). Now, multiplying these fractions: \[ \frac{1}{4} \times \frac{18}{5} = \frac{18}{20} = \frac{9}{10} = 0.9 \] So, the product of 0.25 and 3.6 is 0.9. To quickly verify: 0.25 is a quarter, and when you calculate three-quarters of a whole (which is 0.25 times 3.6), you also find it's equal to 0.9. Simple as pie! 🍰
