Answer 1

1)4/5 * 1/5 = 4/25

2)35/13 * 13/10 =7*1/2=7/2

3)36/7 * 11/21= 12/7 * 11/7=132/49

4)17/15 :17/5 = 17/15 * 5/15 =1/3

Answer 2

1) $\frac{16}{45} *\frac{9}{20} =\frac{2*2*2*2*3*3}{5*3*3*2*2*5} =\frac{2*2}{5*5}=\frac{4}{25} =0,16$

2) $\frac{35}{13} *\frac{13}{10} =\frac{7*5*13}{13*5*2} =\frac{7}{2} =3,5$

3) $\frac{36}{7} :\frac{32}{21} =\frac{36}{7} *\frac{21}{32} =\frac{2*2*3*3*3*7}{7*2*2*2*2*2} =\frac{27}{8} =3\frac{3}{8}$

4) $\frac{17}{15} :\frac{34}{10} =\frac{17}{15} *\frac{10}{34} =\frac{17*2*5}{5*3*17*2} =\frac{1}{3}$
