помогите пожалуйста​

Answer 1

$1)\;4\frac5{12}-3\frac7{18}=4\frac{15}{36}-3\frac{14}{36}=1\frac1{36}=\frac{37}{36}\\\\2)\;\frac{37}{36}:9.25=\frac{37}{36}:9\frac14=\frac{37}{36}:\frac{37}4=\frac{37}{36}\cdot\frac4{37}=\frac19\\\\3)\;\frac19+\frac56=\frac2{18}+\frac{15}{18}=\frac{17}{18}\\\\4)\;0.4+\frac18+0.75=\frac25+\frac18+\frac34=\frac{16}{40}+\frac5{40}+\frac{30}{40}=\frac{51}{40}\\\\5)\;\frac{51}{40}\cdot\frac23=\frac{17}{20}$

$6)\;\frac{\left(4\frac5{12}-3\frac7{18}\right):9.25+\frac56}{\left(0.4+\frac18+0.75\right)\cdot\frac23}=\frac{17}{18}:\frac{17}{20}=\frac{17}{18}:\frac{20}{17}=\frac{10}9=1\frac19$
