Question

Tính bằng cách thuận tiện: 3,12 : 0,25 + 12,48 x 3 - 3,12 x 6

Các bn ơi giải hộ mik với!

Answer 1

    3,12 : 0,25 + 12,48 x 3 - 3,12 x 6

=  3,12 x 4 + 3,12 x ( 4 x 3 ) - 3,12 x 6

= 3,12  x 4 + 3,12 x 12 - 3,12 x 6

= 3,12 x ( 4 + 12 - 6 )

= 3,12 x         10

= 31,2

Answer 2

3,12 : 0,25 + 12,48 x 3 - 3,12 x 6

=3,12 : 1/4 + 3,12 x 4 x 3 - 3,12 x 6

=3,12 x 4 + 3,12 x 12 - 3,12 x 6

=3,12 x (4 + 12 - 6)

=3,12 x 10

=31,2

Answer 3

   3,12 : 0,25 +12,48 x 3 - 3,12 x 6

= 3,12 x 4 + 3,12 x 12 - 3,12 x 6

=3,12 x (4 + 12- 6)

=3,12 x 10

= 31,2

Answer 4

3.12 : 0.25 +12.48 * 3-3.12*6

=3.12 : \(\frac{1}{4}\)+12.48 * 3 -3.12 *6

=3.12 * 4 + 12.48 * 3 - 3.12 *6

=3.12 * ( 4 +6 ) +37.44

=3.12 * 10 + 37.44 

=31.2 + 37.44

=68.64

Answer 5

    3,12 : 0,25 + 12,48 x 3 - 3,12 x 6

=  3,12 x 4 + 3,12 x ( 4 x 3 ) - 3,12 x 6

= 3,12  x 4 + 3,12 x 12 - 3,12 x 6

= 3,12 x ( 4 + 12 - 6 )

= 3,12 x 10

= 31,2
