Помогите решить пожалуйста

1.

1) $\frac{96}{60}= \frac{8*12}{5*12}= \frac{8}{5}=1 \frac{3}{5}$

2) $\frac{1104}{150}= \frac{184*6}{25*6}= \frac{184}{25}=7 \frac{9}{25}$

3) $\frac{196}{64}= \frac{49*4}{16*4}= \frac{49}{16}=3 \frac{1}{16}$

4) $\frac{121}{55}= \frac{11*11}{5*11}= \frac{11}{5}=2 \frac{1}{5}$

2.

1) $\frac{7*12*25}{50*16*49}= \frac{1*3*1}{2*4*7}= \frac{3}{56}$

2) $\frac{10^{3}*16 }{64* 10^{2} } = \frac{10*1}{4*1}= \frac{10}{4}=2 \frac{2}{4}$

3) $\frac{24*48*9}{81*72*96}= \frac{1*1*1}{9*3*2}= \frac{1}{54}$

3.

1) $5- 1\frac{2}{5}= \frac{5}{1}- \frac{7}{5}= \frac{25-7}{5}= \frac{18}{5}=3 \frac{3}{5}$

2) $4 \frac{3}{17}+5 \frac{12}{17}= \frac{71}{17}+ \frac{97}{17}= \frac{71+97}{17}= \frac{168}{17}=9 \frac{15}{17}$
