Question

简便运算:48×73+5.2×730？

Answer 1

48*73+5,2*730
=48*73+52*73
=73*(48+52)
=73*100
7300
5的倒数比它本身少百分之八十.
35*5/7=25 25÷5/6=30 甲数是30.,9,48×73+5.2×730
=48×73+52×73
=（48+52）×73
=100×73
=7300,3,（48+5.2*10）*73=7300,2,48×73+5.2×730=48×73+52×73=(48+52)×73=100×73=7300
4/23×70=4/23×(69+1)=4/23×69+4/23×1=12又4/23
5-1/5=4又4/5
35×5/7=25 25÷5/6=30,1,73×（52+48）
=73×100
=7300
5/1÷5×100％=4％
甲数是30,1,48*73+52*73
=73*（48+52)
=73*100
=7300,0,48×73+5.2×730=48X73+52X73=(48+52)X73=100X73=7300
4/23×70=4/23×(69+1)=4/23×69+4/23×1=12又4/23
5的倒数比它本身少百分之几
1/5/5=1/25=4%
