1.) 2/3 x 4/5 = 8/152.) 1/2 x 3/4 =3/83.) 2/3 x 5/7=10/21To multiply fractions, multiply the numerators (top numbers) together and then multiply the denominators (bottom numbers) together. Then, simplify the resulting fraction if needed.1.) [tex]\frac{2}{2} \times\frac{4}{5}[/tex][tex]=\frac{2\times4}{3\times5}[/tex][tex]=\frac{8}{15}[/tex] (cannot be simplified further)Therefore, 2/3 x 4/5 = 8/152.) [tex]\frac{1}{2} \times\frac{3}{4}[/tex][tex]=\frac{1\times3}{2\times4}[/tex][tex]=\frac{3}{8}[/tex] (cannot be simplified further)Therefore, 1/2 x 3/4 = 3/83.) [tex]\frac{2}{3} \times\frac{5}{7}[/tex][tex]=\frac{2\times5}{3\times7}[/tex][tex]=\frac{10}{21}[/tex] (cannot be simplified further)Therefore, 2/3 x 5/7 =10/21
