Question

tính bằng cách thuận tiện:

13,25 : 0,5 + 13,25 : 0,25 + 13,25 : 0,125 - 13.25: 0,25

Answer 1

13,25 : 0,5 + 13,25 : 0,25 + 13,25 : 0,125
=13.25*2+13.25*4+13.25*8
=13.25*(2+4+8)
=13.25*14
=185.5

Answer 2

\(13,25\div0,25+13,25\div0,25+13,25\div0,125+13,25\div0,25\)

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

\(=13,25\times\left(2+4+8+2\right)\)

\(=13,25\times16\)

\(=212\)

P/s : Tính ra kết quả luôn == Sai thì thôi nha :>

Answer 3

\(13,25\div0,5+13,25\div0,25+13,25\div0,125-13,25\div0,25\)

\(=13,25\cdot2+13,25\cdot4+13,25\cdot8-13,25\cdot4\)

\(=13,25\left(2+4+8-4\right)\)

\(=13,25\cdot10\)

\(=132,5\)

Answer 4

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

= 13,25 x 2 + 13,25 x 4 + 13,25 x 8 - 13,25 x 4

= 13,25 x ( 2 +4 +8 - 4 )

= 13,25 x ( 2+8 )

= 13,25 x 10

=132,5
