\(\frac{36\times45}{6\times5}=\frac{6\times6\times5\times9}{6\times5}=\frac{6\times9}{1}=\frac{54}{1}=54\)

\(\frac{36x45}{6x5}\)

\(=\frac{6x6x5x9}{6x5}\)

\(=6x9\)

a) = 54

b) = 49

a,36*45/6*5=36/6*45/5=6*9=54

b,56*63/9*8=7*7/1*1=49

a) \(\frac{36\cdot45}{6\cdot5}\)

\(=\frac{6\cdot6\cdot5\cdot9}{6\cdot5}\)

\(=6\cdot9\)

a: =36,5x2+36,5x9-36,5

=36,5x10

=365

36,5 : 0,5 + 36,5 \(\times\) 9 -36,5

\(=36,5.2+36,5\times9-36,5\)

\(=36,5\times\left(2+9-1\right)\)

\(=36,5\times10\)

\(=365\)

lm theo cách này nhé :\

36,5 : 0,5 + 36,5  9 -36,5

36,5x2+36,5x9-36,5

=36,5x10

=365

oki :)

a. 125 x 25 x 8

=(125x8) x25

=    1000 x25

= 25000

a. 125 x 25 x 8

= ( 125 x 8 ) x 25 

= 1000 x 25

= 25000

=1000x25=25000

`=1,25xx(1+2+7)=1,25xx10=12,5`

a) = 1,25 x ( 2 + 7 + 1 )

= 1,25 x 10

= 12,5

12,5

(36 + 54) × 7 + 7 × 9 + 7

= 90 × 7 + 7 × 9 + 7

= (90 + 9 + 1 ) × 7

= 100 × 7

= 700

A = 700
