Answer:
1. Ans;
[tex] \frac{1}{3} \times 1 \frac{1}{3} = \frac{1}{3} \times \frac{4}{3} = \frac{4}{9} = 0.4 [/tex]
2. Ans ;
[tex]1 \frac{1}{5} \times \frac{3}{4} = \frac{6}{5} \times \frac{3}{4} = \frac{9}{10} = 0.9[/tex]
3. Ans ;
[tex] \frac{2}{3} \times 1 \frac{3}{5} = \frac{2}{3} \times \frac{8}{5} = \frac{16}{15} = 1 \frac{1}{15} = 1.06[/tex]
4. Ans ;
[tex]2 \frac{1}{2} \times 1 \frac{1}{3} = \frac{5}{2} \times \frac{4}{3} = \frac{10}{3} = 3 \frac{1}{3} = 3.3[/tex]
5. Ans ;
[tex]2 \frac{1}{2} \div \frac{4}{5} = \frac{5}{2} \div \frac{4}{5} = \frac{5}{2} \times \frac{5}{4} = \frac{25}{8} = 3 \frac{1}{8} = 3.125[/tex]
6. Ans ;
[tex]9 \div 1 \frac{1}{9} = 9 \div \frac{10}{9} = 9 \times \frac{9}{10} = \frac{81}{10} = 8 \frac{1}{10} = 8.1[/tex]
7. Ans ;
[tex]2 \frac{1}{2} \div 3 \frac{1}{3} = \frac{5}{2} \div \frac{10}{3} = \frac{5}{2} \times \frac{3}{10} = \frac{3}{4} = 0.75[/tex]
8. Ans ;
[tex]7 \frac{1}{2} \div 1 \frac{2}{3} = \frac{15}{2} \div \frac{5}{3} = \frac{15}{2} \times \frac{3}{5} = \frac{9}{2} = 4 \frac{1}{2} = 4.5[/tex]
I hope I helped you^_^
