(0,5/1,25+ 3 1/2 *1,03-1,005)/(2 1/16- 1 23/24)=?
помогите по действиям(

Answer 1

$1)\frac{0,5}{1,25} =0,4\\\\2)3\frac{1}{2}*1,03=3,5*1,03=3,605\\\\3)0,4+3,605-1,005=4,005-1,005=3$

$4)2\frac{1}{16}-1\frac{23}{24}=2+\frac{1}{16}-1-\frac{23}{24}=(2-1)+(\frac{1}{16}-\frac{23}{24})=1+\frac{1*3-23*2}{48}=1+\frac{3-46}{48}=1-\frac{43}{48}=\frac{5}{48}\\\\5)3:\frac{5}{48}=3*\frac{48}{5}=\frac{144}{5}=28,8\\\\Otvet:\boxed{28,8}$
