\(20,18.7,5+20,18+20,18:2\\ =20,18.\left(7,5+1+0,5\right)\\ =20,18.9\\ =181,62\)
\(20,18\times7,5+20,18+20,18:2\)
\(=20,18\times7,5+20,18\times1+20,18\times0,5\)
\(=20,18\times\left(7,5+1+0,5\right)\)
\(=20,18\times9\)
\(=181,62\)
a,20,18×7,5+20,18+20,18+20,18:2a,20,18×7,5+20,18+20,18+20,18:2
=20,18×7,5+20,18×1+20,18×1+20,18×0,5=20,18×7,5+20,18×1+20,18×1+20,18×0,5
=20,18×(7,5+1+1+0,5)=20,18×(7,5+1+1+0,5)
=20,18×(8,5+1+0,5)=20,18×(8,5+1+0,5)
=20,18×(9,5+0,5)=20,18×(9,5+0,5)
=20,18×10=20,18×10
=201,8 đây nhé bạn
20,18 x 7,5 + 20,18 + 20,18 : 2
= 20,18 x 7,5 + 20,18 x 1 + 20,18 : 0,5
= 20,18 x ( 7,5 + 1 + 0,5 )
= 20,18 x 9
= 181,62
