问题描述:
脱式计算(能简算的用简算) 2/3=三分之二
36* 11/6 * 7/44 35/9 * 4/15+35/9 *11/15 50*(7/5-4/3) 24/5 * 11/8+ 13/10 *11/8 (27/4-19/5)÷4/5 (9/14*29+58/9*29)*5/4
答
36* 11/6 * 7/44
=42/4
=21/2
=10.5
35/9 * 4/15+35/9 *11/15
=35/9*(4/15+11/15)
=35/9
50*(7/5-4/3)
=50*1/15
=10/3
24/5 * 11/8+ 13/10 *11/8
=11/8*(24/5+13/10)
=11/8*61/10
=671/80
(27/4-19/5)÷4/5
=(135-76)/20*5/4
=59/20*5/4
=59/16
(9/14*29+58/9*29)*5/4
=29*5/4*(9/14+58/9)
=145/4*(81+58*14)/(14*9)
=145*893/504
=129485/504.
