A ) 1,92 x 104 -1,92 : 0,25 = 1,92 x 104 - 1,92 x 4
= 1,92 x ( 104 - 4 )
= 1,92 x 100
= 192
B/ 35,7 :0,125 + 35,7 x 92 = 35,7 x 8 + 35,7 x 92
= 35,7 x ( 8 + 92 )
= 35,7 x 100
= 2570
Bài làm
\(A=1,92x104-1,92:0,25\)
\(A=1,92x104-19,2x\frac{100}{25}\)
\(A=1,92x104-1,92x4\)
\(A=1,92x\left(104-4\right)\)
\(A=1,92x100\)
\(A=192\)
Vậy \(A=192\)
\(B=35,7:0,125+35,7x9,2\)
\(B=35,7x\frac{4}{5}+35,7x9,2\)
\(B=35,7x\left(\frac{4}{5}+\frac{92}{10}\right)\)
\(B=35,7x\left(\frac{4}{5}+\frac{46}{5}\right)\)
\(B=35,7x\frac{50}{5}\)
\(B=35,7x10\)
\(B=357\)
Vậy \(B=357\)
