27*18*15=7290
3.8*2.5*4=38
1.9*1.4*1.5=3.99
\(\frac{4}{3}x\frac{5}{4}x\frac{2}{3}=\frac{10}{9}\)
15.5*6.4*10=992
1.75*0.4*0.8=0.56
8*5*4.5=180
2*0.5*0.75=0.75
(15-12)*10.5*8=252
10*4.5*12=540
= 7290
= 38
= 3,99
= 10 / 9
= 992
= 0,56
= 180
= 0,75
= 252
= 540
\(8\frac{2}{7}-\left(1\frac{1}{6}+25\%\right)=\frac{58}{7}-\left(\frac{7}{6}+\frac{1}{4}\right)=\frac{58}{7}-\frac{17}{12}=\frac{577}{84}\)
\(4\frac{3}{4}+\left(-0,37\right)+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{12}\)
\(=\frac{19}{4}+\left(-\frac{83}{20}\right)+\frac{37}{12}=\frac{3}{5}+\frac{37}{12}=\frac{221}{60}\)
\(8\frac{2}{7}-\left(1\frac{1}{6}+25\%\right)=\frac{58}{7}-\left(\frac{7}{6}+\frac{1}{4}\right)=\frac{58}{7}-\frac{17}{12}=\frac{577}{84}\)
\(\left(\frac{12}{32}+\frac{5}{-20}-\frac{10}{24}\right):\frac{2}{3}=\left(\frac{1}{8}-\frac{10}{24}\right):\frac{2}{3}=-\frac{7}{24}:\frac{2}{3}=-\frac{7}{16}\)
\(4\frac{1}{2}:\left(2,5-3\frac{3}{4}\right)+\left(\frac{1}{2}\right)^2=\frac{9}{2}:\left(2,5-\frac{15}{4}\right)+\frac{1}{4}=\frac{9}{2}:-\frac{5}{4}+\frac{1}{4}=-\frac{18}{5}+\frac{1}{4}=-\frac{67}{20}\)
\(\frac{12}{2}+2,5+2-4\)
= 6 + 2,5 + 2 - 4
= 8,5 + 2 - 4
= 10,5 - 4
= 6,5
12/2+2,5+2-4
=6+2,5+2-4
=6,5
