Question

UJIII PAS SEMESTER 2​

Answer 1

Penjelasan dengan langkah-langkah:

1) B

jarak sebenarnya = 5 x 40.000.000

100.000

= 5 x 400

= 2.000 km

2) A

sisa = 1 – ⅓ – 2/5

= 15 – 5 – 6

15

= 4

15

3) D

A : B = 3 : 2

B : C = 5 : 7

A : C = (3×5) : (2×7)

A : C = 15 : 14

4) D

Jarak sebenarnya = 8 x 35.000

100.000

= 280.000

100.000

= 2,8 km

5) D

Jarak = 72 x 5

4

= 18 x 5

= 90 km

6) B

80 x 15 = (80 + 20) x h

1.200 = 100h

h = 1.200

100

h = 12 hari

7) B

15 x 12 = 9 x 12 + 4 x 0 + 2p

180 = 108 + 0 + 2p

2p = 180 – 108

p = 72

2

p = 36

tambahan = 36 – 12

tambahan = 24 pekerja

8) B

30 x 34 = 9 x 34 + 4 x 0 + 17 x p

(30 – 9) x 34 = 0 + 17p

21 x 34 = 17p

p = 21 x 34

17

p = 21 x 2

p = 42

tambahan = 42 – 34

tambahan = 8 pekerja

9) B

jumlah siswa = 120

siswa kidal = 16 –

bukan kidal = 104

Rasio kidal dan bukan = 16 : 104

= 16 : 104

8 8

= 2 : 13

= 2
