When multiplying fractions, how do you obtain the new numerator?

To obtain the new numerator when multiplying fractions, you multiply the numerators of the fractions together. For example, if you have two fractions like ( \frac{a}{b} ) and ( \frac{c}{d} ), the new numerator in the resulting product ( \frac{a \cdot c}{b \cdot d} ) comes from multiplying ( a ) and ( c ). This process is a fundamental principle of fraction multiplication, which states that the product of two fractions is achieved by multiplying the numerators to form the new numerator and multiplying the denominators to form the new denominator.

This understanding is essential for performing calculations with fractions accurately and allows you to work with more complex mathematical operations involving fractions in various contexts. Knowing how the multiplication of numerators works lays the groundwork for further math skills necessary in both nursing and other fields.
