Question

помагите пожалуйста​

Answer 1

1) $\frac{6*15}{5*12} = \frac{3}{2} = 1\frac{1}{2}$

2) $\frac{11*9}{15*22} = \frac{3}{5*2} = \frac{3}{10}$

3) $\frac{18*21}{14*36}$ $= \frac{3}{2*2} = \frac{3}{4}$

4) $\frac{45*17}{17*35} = \frac{9}{7} = 1\frac{2}{7}$

5) $\frac{81*12}{24*45}$ $= \frac{9}{2*5} = \frac{9}{10}$

6) $\frac{56*16}{48*49} = \frac{8}{3*7} = \frac{8}{21}$
