Question

(750×308-375×208):(179×5+630:6)=
[3×100-(5×10×2-8×10)]×25:10=
450:6×5+(38×100-2879)=

Answer 1

(750*308-375*308):(179*5+630:6)=
(231000-115500):(895+105)=
115500:1000=115,5

[3*100-(5*10*2-8*10)]*25:10=
[300-(100-80)]*25:10=
(300-20)*25:10=
280*25:10=
7000:10=700

450:6*5+(38*100-2879)=
75*5+(3800-2879)=
375+921=1296
