To multiply fractions, you should

Explanation:
Multiplying fractions means multiplying the top numbers together and the bottom numbers together. The rule is to multiply the numerators to get the new numerator and multiply the denominators to get the new denominator. For example, (2/5) times (3/4) gives (2×3)/(5×4) = 6/20, which simplifies to 3/10. This shows why the correct approach is to multiply the numerators and the denominators. Adding the numerators and adding the denominators is how you add fractions, not multiply. Cross-multiplying is used in solving proportions or comparing fractions, not for the direct multiplication of two fractions.
