Answer:

TO MULTIPLY FRACTIONS YOU NEED TO MULTIPLY NUMERATOR BY NUMERATOR AND DENOMINATOR BY DENOMINATOR.

1.

[tex] \frac{3}{8} \times \frac{5}{6} = \frac{15}{48} \div 3 = \frac{5}{16} [/tex]

2.

[tex] \frac{4}{5} \times \frac{1}{2} = \frac{4}{10} \div 2 = \frac{2}{5} [/tex]

3.

[tex] \frac{3}{10} \times \frac{3}{4} = \frac{9}{40} [/tex]

4.

[tex] \frac{3}{5} \times \frac{2}{3} = \frac{6}{15} \div 3 = \frac{2}{5} [/tex]

5.

[tex] \frac{7}{12} \times \frac{4}{7} = \frac{28}{84} \div 28 = \frac{1}{3} [/tex]

6.

[tex] \frac{3}{7} \times \frac{4}{21} = \frac{12}{147} \div 3 = \frac{4}{49} [/tex]

7.

[tex] \frac{4}{5} \times \frac{5}{12} = \frac{20}{60} \div 20 = \frac{1}{3} [/tex]
