简便运算！！！急急急！！！！写出过程！！！

（38+14+16）*24

0.47*1.25+114+0.63*125%

（3.75+1.85）*40-4.2*25

【435-1.2*（23+1.5）】/3

Answer 1

（38+14+16）*24
=（38+40）×24
=78×24
=1872
0.47*1.25+114+0.63*125%
=0.47×1.25+0.63×1.25+114
=（0.47+0.63）×1.25+114
=1.1×1.25+114
=1.375+114
=115.375
（3.75+1.85）*40-4.2*25
=5.6×40-4×25-0.2×25
=224-100-5
=124-5
=119
【435-1.2*（23+1.5）】/3
=【435-1.2*24.5】/3
=【435-29.4】/3
=405.6÷3
=135.2
