kết quả ra nhìu lắm bạn ạ

kết quả là 29,25

13,25 :0,5+13,25:0,25+13,25:0,125

=13,25:(0,5+0,25+0,125)=13,25:0,875=13,25:7/8=13,25x8/7=106/7=15,14285714

\(13,25:0,5+13,24:0,25+13,25:0,125\)

\(=13,25\times2+13,24\times4+13,25\times8\)

\(=13,25\times\left(2+8\right)+13,24\times4\)

\(=13,25\times10+52,96\)

\(=132,5+52,96\)

\(=185,46\)

32,6x64+40x32,6-32,6:0,25

=32,6x64+40x32,6-32,6x4

=32,6x(60+40-4)

=32,6x100

=3260

32,6*64+40*32,6-32,6:0,25  ( chia 0.25 là nhân 4 ) 

32,6 * ( 64 + 40 ) - 32.6 x 4 

32,6 * 104 - 130.4

3390.4 - 130.4 

3260 

ủng hộ mk nha 

\(32,6.64+40.32,6-32,6:0,25\)

\(=32,6.64+40.32,6-32,6:\frac{1}{4}\)

\(=32,6.64+40.32,6-32,6.4\)

\(=32,6.\left(64+40-4\right)\)

\(=32,6.100\)

\(=3260\)

Hok tốt

198×27+198×72+198

=198×27+198×72+198×1

=198×(27+72+1)

=198×100

=19800

=198x(27+72+1)

=198x100=19800

vậy..............

k mình nha
