Question

помогите по матеше зарание спасибо

Answer 1

$\frac{\left(2\frac3{25}+9,6-5,72\right):0,15}{10,92:(2,6\cdot0,5)-0,4}\\1)\;2\frac3{25}+9,6=2\frac{12}{100}+9,6=2,12+9,6=11,72\\2)\;11,72-5,72=6\\3)\;6:0,15=6:\frac{15}{100}=6\cdot\frac{100}{15}=\frac{600}{15}=40\\4)\;2,6\cdot0,5=1,3\\5)\;10,92:1,3=8,4\\6)\;8,4-0,4=8\\7)\frac{40}8=5\\\\\frac{\left(2\frac3{25}+9,6-5,72\right):0,15}{10,92:(2,6\cdot0,5)-0,4}=5$
