помогите нужно сократить дробь ​

Answer 1

Ответ:

$\frac{ {2}^{3} \times {3}^{3} \times 5 }{ {3}^{2} \times {2}^{3} } = \frac{ {3}^{3} \times 5 }{ {3}^{2} } = 3 \times 5 = 15$

$\frac{45 \times {4}^{2} }{80 \times {3}^{2} } = \frac{9 \times {4}^{2} }{16 \times {3}^{2} } = \frac{ {3}^{2} \times {4}^{2} }{ {4}^{2} \times {3}^{2} } = 1$
