=(32x1,25) x (0,99 x 25)

=40 x 24,75

= 31, 68 x 25 x 1,25

=    792   x    1, 25

=       990

đây nhé .!

.

\(32\times0,99\times25\times1,25\)

\(\Rightarrow\left(32\times1,25\right)\times\left(0,99\times25\right)\)

\(\Rightarrow40\times24,75\)

\(\Rightarrow990\)

(125.37.32):4=(125:4).(37:4).(32:4)=5.9,25.8=9,25.(5.8)=9,25. 40=9,25.4.10=37.10=370

   45 . 25 . 32 . 1,25

= 45 . 25 . (32 . 1,25)

= 45 . 25 . 40

= 45 . (25 . 40)

= 45 . 1000

=45000

45 x 25 x 32 x 1,25 = 45 x 25 x 4 x 8 x 1, 25 = 45 x 100 x 8 x 1,25 = 45 x 8 x 1, 25 x 100 = 45 x 8 x 125 = 45 x 1000 = 45000

=45000 nhé

6*x+7.19*x=3.558

(6+7.19)*x=3.558

13.19*x=3.558

x=3.558/13.19

=0.2697498105

tính nhanh

0,8 x 0,4 x 1,25 x 25 + 0,725 + \(\frac{0,25}{2,25\times4\times8\times25}\)

= (0,8 x 0,4) x (1,25 x 25) + 0,725 + \(\frac{0,25}{2,25\times4\times8}\)

= 0,32          x          31,25 + 0,725 + \(\frac{0,25}{2,25\times4\times8}\)

= 10                                   + 0,725 + \(\frac{0,25}{2,25\times4\times8}\)

= 10                                   +         18,725

= 28,725

Hk tốt,

k nhé

Chắc ko đó bạn

32 x 24 + 32 x 76

= 32 x (24 + 76)

= 32 x 100

= 3200

32 x 24 + 32 x 76

= 32 x ( 24 + 76 )

= 32 x 100

= 3200

32 x 24 + 32 x 76 = 3200

\(\frac{12}{15}\times\frac{22}{47}+\frac{25}{47}:\frac{15}{12}\)

\(\frac{12}{15}\times\frac{22}{47}+\frac{25}{47}\times\frac{12}{15}\)

\(=\frac{12}{15}\times\left(\frac{22}{47}+\frac{25}{47}\right)\)

\(=\frac{12}{15}\times\frac{22+25}{47}\)

\(=\frac{12}{15}\times1=\frac{12}{15}\)

32 x 1,25 x 25 x (54/10 x 8,7 + 5,4 x 3,3 - 10,8)

= (32 x 25) x 1,25 x (5,4 x 8,7 + 5,4 x 3,3 - 10,8)

= 800 x 1,25 x (5,4 x 8,7 + 5,4 x 3,3 - 5,4 x 2)

=   1000 x [ 5,4 x (8,7 + 3,3 - 2) ]

= 1000 x (5,4 x 10)

= 1000 x 54

= 54000
