Can you give me some example in multiplying fraction?

Sure! To multiply fractions, you simply multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together. For example, if you multiply ( \frac{2}{3} ) by ( \frac{4}{5} ), you calculate ( 2 \times 4 = 8 ) for the numerator and ( 3 \times 5 = 15 ) for the denominator, resulting in ( \frac{8}{15} ). Another example is ( \frac{1}{2} \times \frac{3}{4} = \frac{1 \times 3}{2 \times 4} = \frac{3}{8} ).
