\(53.68x15.6-53.68x5.6\)
\(=53.68x\left(15.6-5.6\right)\)
\(=53.68x10\)
\(=536.8\)
Nhớ k mk nha bn minh tuyệt vọng lắm!
53,68*15,6-53,68*5,6
=53,68* (15,6-5,6)
=53,68-10
=5,368
1) \(A=20,11\times2,4+1,4\times20,11\times2-10,05\times10,4\) (tách 40,22 = 20,11 x 2)
\(=20,11\times\left(2,4+1,4\times2\right)-10,05\times10,4\)
\(=20,11\times5,2-10,05\times5,2\times2\) (tách 10,4 = 5,2 x 2)
\(=5,2\times\left(20,11-20,1\right)\)
\(=5,2\times0,01\)
\(=0,052\)
\(90872:296=307\)
\(6-\frac{3}{7}\)X \(\frac{14}{9}=\frac{124}{23}\)
\(\frac{3}{4}\)X \(\frac{4}{7}=\frac{3}{7}\)X \(\frac{3}{4}+\frac{3}{4}=\frac{9}{28}+\frac{3}{4}=\frac{15}{14}\)
34,67+19,82+43,65+56,35+73,33+86,08
=(34,67+73,33)+(19,82+86,08)+(43,65+56,35)
=108+105,9+100
=313,9

C1: \(A=\left(\frac{36}{6}-\frac{4}{6}+\frac{3}{6}\right)-\left(\frac{150}{30}+\frac{50}{30}-\frac{45}{30}\right)-\left(\frac{18}{6}-\frac{14}{6}+\frac{15}{6}\right)\)
\(=\frac{35}{6}-\frac{155}{30}-\frac{19}{6}=\frac{35}{6}-\frac{31}{6}-\frac{19}{6}=-\frac{15}{6}=-2\frac{1}{2}\)
C2: \(6-\frac{2}{3}+\frac{1}{2}-5-\frac{5}{3}+\frac{3}{2}-3+\frac{7}{3}-\frac{5}{2}\)
\(=\left(6-5-3\right)-\left(\frac{2}{3}+\frac{5}{3}-\frac{7}{3}\right)+\left(\frac{1}{2}+\frac{3}{2}-\frac{5}{2}\right)\)
\(=-2-0-\frac{1}{2}=-2\frac{1}{2}\)
36,67+13,92+43,65+65,33+86,08+56,35=[36,67+65,33]+[13,92+86,08]+[43,65+56,35]
=102+100+100
=302
