Answer:

You have to do the Keep, Change, Flip solution

Keep the first term, Change the sign, Flip the last term

Step-by-step explanation:

1.

[tex] \frac{6}{9} \times \frac{5}{2 } = \frac{30}{18} = \frac{10}{6} = \frac{5}{3} [/tex]

2.

[tex] \frac{3}{8} \times \frac{12}{6} = \frac{36}{48} = \frac{3}{4} [/tex]

3.

[tex] \frac{4}{10} \times \frac{4}{3} = \frac{16}{30} = \frac{8}{15} [/tex]

4.

[tex] \frac{1}{9} \times \frac{10}{8} = \frac{10}{72} = \frac{5}{36} [/tex]

5.

[tex] \frac{2}{12} \times \frac{8}{3} = \frac{16}{36} = \frac{4}{9} [/tex]

6.

[tex] \frac{9}{14} \times \frac{2}{1} = \frac{18}{14} = \frac{9}{7} [/tex]

7.

[tex] \frac{3}{4} \times \frac{5}{3} = \frac{15}{12} = \frac{5}{4} [/tex]

8.

[tex] \frac{1}{8} \times \frac{3}{2} = \frac{3}{16} [/tex]

9.

[tex] \frac{1}{3} \times \frac{2}{1} = \frac{2}{3} [/tex]

10.

[tex] \frac{3}{15} \times \frac{5}{2 } = \frac{15}{30} = \frac{1}{2} [/tex]
