Answer 1

Explicação passo-a-passo:

1. 25+(15+6:3)×5-10
2. 25+17×5-10
3. 25+85-10
4. 110-10

100

2. 45 : ( 3 x 2 + 9) =

45:(6+9)

45:15

3

3. 4x( 32: 8 + 6)+100 – (3 x 20 + 30) =

4×(4+6)+100-(60+30)

4×10+100-(60+30)

4×10+100-90

40+100-90

140-90

50

4. 5 x ( 8 + 12 – 6 ) : 7 =

5×(20-6):7

5×14:7

70:7

10

5. (8 + 6 : 3) x 10 =

( 8+2)×10

100

6. 132 : ( 7 – 1 ) x ( 18 – 7 )=

132:6+11

132 :66=2

66 e a metade de 132

7. (7 x 6 + 8) : ( 38 – 7 x 4)=

(42+8):38-28=

50:10=

10

espero que vc consiga fazer o restô
