Answer 2

Materi : Pecahan

Soal Nomor 2

Bagian B

0,58 + 1,2 + 6/15 - 1,6

= 0,58 + 1,20 + 0,20 + 1,60

= (0+1),(5+2+2+6)(8+0+0+0)

= 1,(15)(8)

= (1+1),(5)(8)

= 2,58

Bagian C

0,42 ÷ 0,6 - 0,65 × 1/13

= 42/10 × 10/6 - 65/100 × 1/13

= 42/6 - 5/100

= 7 - 0,05

= 6,95

Soal Nomor 3

Bagian A

2 - 0,68 + 1,25 ÷ 0,5

= 1,32 + 125/100 × 10/5

= 1,32 + 25/10

= 1,32 + 2,5

= 3,82

Bagian B

0,4 × 1,26 + 0,72 ÷ 8

= 4/10 × 126/100 + 72/100 × ⅛

= 4(126)/1000 + 9/100

= 504/1000 + 9/100

= 0,504 + 0,09

= 0,594

Bagian C

9 × 0,2 - 1,6 ÷ 4

= 9 × 2/10 - 16/10 × ¼

= 18/10 - 4/10

= 1,8 - 0,4

= 1,4

Soal Nomor 4

K = 2( p + l )

3K = ( 2 × 3 )( 12 m + 8,5 m )

3K = 6( 20,5 m )

3K = 120 + 3,0 m

3K = 123 m

Soal Nomor 5

3,5 + 1¼ - 2 - 2,5

= ( 3 + 1 - 2 - 2 ),(5+2-5)(0+5-0)

= ( 4 - 4 ),(2)(5)

= 0,25

Semoga bisa membantu
