Вычислите. 600 ÷ 3 × (380 + 120 ÷ 10)= ?

2100 - 450 ÷ 45 × 2 = ?

2100 - 450 ÷ (45 × 2) = ? Решите Пж!

Answer 1

600:3*(380-120:10)=200*(380-12)=200*368=73600
2100-450:45*2=2100-10*2=2100-20=2080
2100-450:(45*2)=
450:90=5
2100-5=2095

Answer 2

600:3*(380+120:10)=78400 1)120:10=12. 2)380+12=392. 3)600:3=200. 4)392*200=78 400. И. 2100-450:45*2=2080 1)450:45=10. 2)10*2=20. 3)2100-20=2080. И. 2100-450:(45*2)=2095 1)45*2=90 2)450:90=5 3)2100-5=2095
