Question

43 2/3 : 4 20/27 помогите ​

Answer 1

Ответ:

1) $22\frac{6}{7} * 2\frac{11}{40} = \frac{160}{7}* \frac{91}{40} = \frac{4}{7} * \frac{91}{1}= \frac{4}{1} * \frac{13}{1}=4 * 13 = 52$

2) $43\frac{2}{3}:4\frac{20}{27}= \frac{131}{3} :\frac{128}{27} = \frac{131}{3} * \frac{27}{128} = \frac{131}{1} * \frac{9}{128} = \frac{1179}{128} = 9\frac{27}{128}$
