tinh nhanh.2,45 x 46 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

Answer 1

=2.45x(46+54)+8x(0.75+0.5)

=2.45x100+8x1.25

=245+10=255

Answer 2

2,45 x 46 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

= 2,45 x ( 46 + 54 ) + 8 x ( 0,75 + 0,5 )

= 2,45 x 100 + 8 x 1,25

= 245 + 10

= 255

Answer 3

2,45 x 46 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

= 2,45 x (46+54) + 8 x 0,75 + 0,5 x 8

= 2, 45 x 100 + 6 + 4

= 255

Answer 4

\(=2,45.\left(46+54\right)+8.\left(0,75+0,5\right)\)

\(=2,45.10+8.1,25\)

\(=24,5+10\)

\(=34,5\)

Answer 5

sorry 46+54 =100 thiếu 1 số 0

Answer 6

     2,45 x 46 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

=2,45 x (46 + 54) + 8 x (0,75 + 0,5)

=2,45 x 100 + 8 x 1,25

=245 + 10 = 255

Answer 7

2,45 x 46 + 8 x 0.75 +54 x 2,45 + 0.5 x 8

( 2,45 x 46 + 54 x 2,45 )+( 8 x 0,75 + 0,5 x 8 )

2,45 x ( 46 + 54 ) + 8 x ( 0,75 + 0,5 )

2,45 x 100 + 8 x 1,25

245 +10 

=255

T.i.c.k cho mk nha

Answer 8

\(2,45\times46+8\times0,75+54\times2,45+0,5\times8\)

\(=2,45\times\left(46+54\right)+8\times\left(0,75+0,5\right)\)

\(=2,45\times100+8\times1,25\)

\(=2,45\times100+10\)

\(=245+10\)

\(=255\)

Answer 9

  2,45x46+8x0,75+54x2,45+0,5x8

=2,45x(46+54)+8x(0,75+0,5)

=2,45x100+8x1,25

=245+10

=255

Answer 10

2,45 x 36 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

= 2,45 x ( 46 + 54 ) + 8 x ( 0,75 + 0,5 )

= 2,45 x 100 + 8 x 125 

= 245 + 10

= 255

Answer 11

=2,45*[46+54]+[0,75+0,5]*8

=2,45*100+1,25*8

=245+1000

=1245

Answer 12

2,45 x 46 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

= 2,45 x ( 46 + 54 ) + 8 x ( 0,75 + 0,5 )

= 2,45 x 100 + 8 x 1.25

= 245 + 10 = 255.

Answer 13

2,45 x 46 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

= 2,45 x ( 46 + 54 ) + 8 x ( 0,75 + 0,5 )

= 2,45 x 100 + 8 x 1.25

= 245 + 10 = 255.

Answer 14

2,45 x 46 + 8 x 0,75 + 54 x 2,45 + 0,5 x 8

= 2,45 x ( 46 + 54 ) + 8 x ( 0,75 + 0,5 )

= 2,45 x 100 + 8 x 1.25

= 245 + 10 = 255.
