Penjelasan dengan langkah-langkah:

1)

a. 5/12 = 5 ÷ 12 = 0,416 = 416%

b. 4/9 = 4 ÷ 9 = 0,444 = 444%

c. 3/8 = 3 ÷ 8 = 0,375 = 375%

d. 3/7 = 3 ÷ 7 = 0,428 = 428%

Jawaban = C

2)

= -15 + 28 - (-17)

= 13 + 17

= 30 (D)

3)

= (-12) ÷ 3 + 8 × (-5)

= (-4) + (-40)

= -44 (A)

4)

= 4 - (1,2 + 0,8)

= 4 - 2,0

= 2,0 Kg (A)

5)

= 4,23 - 2,138

= 4,230 - 2,138

= ¹ ¹² ¹⁰

4,230

2,138 -

2,092
