计算下面各题，能简算的要简算。谢谢，要过程，急急急。

3.16×238－116×2.38 11分之5×[(5分之2＋3分之1)÷6分之5]

Answer 1

您好：

3.16×238－116×2.38
=3.16×238－1.16×238
=(3.16-1.16)x238
=2x238
=476

11分之5×[(5分之2＋3分之1)÷6分之5]
=5/11x(11/15x6/5)
=5/11x6/5x11/15
=6/11x11/15
=2/5

Answer 2

3.16×238－116×2.38
=3.16 x 238 - 1.16 x 238
=( 3.16-1.16) x 238
= 2 x 238
=476

11分之5×[(5分之2＋3分之1)÷6分之5]
= 5/11 x ( 2/5 x 6/5 + 1/3 x 6/5 )
=5/11 x ( 12/25 + 2/5)
= 5/11 x 12/25 + 5/11 x 2/5
= 12 / 55 + 2/11
= 12 / 55 + 10/55
= 22 / 55
= 2/5

Answer 3

3.16×238－116×2.38
= 316×2.38－116×2.38
=2.38×（316-116）
=2.38×200
=476
11分之5×[(5分之2＋3分之1)÷6分之5]

=5/11×（2/5×6/5+1/3×6/5)
=5/11×（12/25+2/5)
=5/11×12/25+5/11×2/5
=2/5
