Answer 1

a) 485750+56832:8
=485750+7104
=492854

b) 50x(51340-3407)
=50 x 47933
=2396650

c) 713230-96360:30
=713230-3212
=710018

d) 500x20+80x105
=10000+8400
=18400

e) 46800:400-400:50
=117-8
=109

f) (21007+8993):6000x67
=(21007+8993):402000
=30000:402000
=0,007

g) (13500+6500):(2458+7542)
=20000:10000
=2

h) (1000000-1000):(1000-100)
=999000:900
=1110

Answer 2

A. 485750+56832:8= 56832:8=7104+485750=492854 ;
B. 50×(51340-3407)= 51340-3407=47933x50= 2396650 ;C. 713230-96360:30= 96360:30= 3212.. 713230-3212=710018 ;
D. 500×20+80×105= 500x20= 10000+8400=18400 ;
E. 46800:400-400:50= 46800:400=117-8=109 ;
F. (21007+8993):6000×67= 21007+8993=30000:402000=0.007 ;
G. (13500+6500):(2458+7542)= 20000:10000= 2 ;
H. (1000000-1000):(1000-100)= 999000: 900= 1110..
