Answer 1

14. Di foto
15. 3:4:5
A : B : C
Budi 400.000,00 : 100.000, 00 = 4
Amir = 3 × 100.000, 00 = 300.000, 00
Cici = 5 × 100.000, 00 = 500.000, 00
= 300.000, 00 + 500.000, 00 = 800.000, 00 (C.)
16. 360 km = 360.000.000 : 9 = 4.000.000 (D.)
17. 27² - 11² + √289
= 729 - 121 + 17
= 625 ( A. )
18. √529 = 23 cm (c.)

Answer 2

14. 96 = 2^5 × 3
69 = 3 × 23
FPB = 3 (cari pangkat yg kecil) (A)

15.
U. Amir = 3/4 × 400.000 = 300.000
U. Cici = 5/4 × 400.000 = 500.000
Jumlah = 800.000 (C)

16.
J. sebenarnya / J. peta
= 360 km / 9 cm
= 36.000.000 / 9
= 4.000.000
= 1 : 4.000.000 (D)

17.
729 - 121 + 13 = 625 (A)

18.
L = s × s
s = √L
s = √529
s = 23 (C)
