Answer:

1.) 12

2.) [tex]- 7\frac{70}{9}[/tex] or -7.7

3.) 24

4.) 72

5.) 8

Step-by-step explanation:

1.) 42 ÷ 6 + 5

= 7 + 5

= 12

2.) [tex]\frac{6}{9}[/tex]× [tex]\frac{1}{3}[/tex] - 8

= [tex]\frac{2}{9}[/tex] - 8

= [tex]- 7\frac{70}{9}[/tex] or -7.7

3.) 8 x 3 + 40 ÷ 5 - 8

= 24 + 8 - 8

= 24

4.) 64 + 2 (6-2)

= 64 + 2 x 4

= 64 + 8

= 72

5.) 4 (2 + 4) ÷ 3

= 4 x 6 ÷ 3

= 8
