Answer 1

Salut!

a) 5 + 55-5:5* (7 + 8 + 3 + 5 + 7): 10=

= 5 + 55 - 5 ÷ 5* 30 : 10=

= 5 + 55 - 5 + 5 * 3=

= 5 + 55 - 5 + 15=

= 60 - 5 + 15=

= 55 + 15=

= 70.

b) (2 800 – 2 200): 100 + 10 x 60 + (1 200: 3-15 * 5)=

= 600 : 100 + 10 × 60 + (400 - 75)=

= 6 + 600 + 325=

= 606 + 325=

= 931.

c) 3 874 x 15 – 1 916 x 22 + 10 450 : 25=

= 57 705 - 42 152 + 418=

= 15 553 + 418=

= 15 971.

d) [2 100 : (225 – 500 : 4) + (84: 2 x 0)] x 100 : 10:10=

= [ 2 100: (225 - 125) + ( 84 : 0)] ×100 : 10 : 10=

= (2 100 : 100 + 84) × 100 : 10 : 10=

= (21 +84) × 100 : 10 : 10=

= 105 × 100 : 10: 10=

= 10500 : 10 : 10=

= 1050 : 10=

= 105.

Sper ca ți-am fost de ajutor=)

Succes la școală!
