Jawaban:

a. [tex] \frac{ \: (60 \times 2) + 75 + 54 + 84 + 50 + 68 + 85 \: \: }{8} = \frac{536}{8} = 67[/tex]

b. 55 + 47 + (60x2)+ (75x2) + 80 + 95 + 50 + 63= 660/10= 66

c. 100 + 37 + 30 + 62 + 65 + 70 + 44 + 60 + 75 + 50 + 28= 621/11= 56,45

a. = ( 60 + 75 + 54 + 60 + 84 + 50 + 68 + 85 ) ÷ 8

= 536 ÷ 8

= 67 ✓

b. = ( 55 + 47 + 60 + 75 + 80 + 95 + 60 + 75 + 50 + 63 ) ÷ 10

= 660 ÷ 10

= 66 ✓

c. = ( 100 + 37 + 80 + 62 + 65 + 70 + 44 + 60 + 75 + 50 + 28 ) ÷ 10

= 671 ÷ 11

= 61 ✓
