a). 4/5 * 2/3 = 8/15 (m2)
b). 3 * 9/10 = 27/10 = 2 7/10 (dm2)
c). 3/4 * 2/9 = 2/12 = 1/6 (cm2)
[tex]a)\frac{4}{5}m*\frac{2}{3}m = \frac{8}{15} m^{2}[/tex]
[tex]b) \frac{9}{10}dm*3dm = \frac{9}{10} dm*\frac{3}{1} dm=\frac{27}{10} dm^{2}=2\frac{7}{10} dm^{2}[/tex]
[tex]c)\frac{3}{4}cm*\frac{2}{9}cm=\frac{6}{36}cm^{2}=\frac{1}{6}cm^{2}[/tex]
