Bab : Operasi Bilangan
Sub Bab : Perkalian, Penjumlaham, dan Pembagian Bilangan

Pembahasan:

1). 12,5 : 0,5 × 7
= 125/10 : 5/10 × 7/1
= 25/2 : 1/2 × 7/1
= 25/2 : 7/2
= 25/2 × 2/7
= 50/14
= 25/7
= 3 4/7 → Jwbnya

2). 15 + (32 × n) : 4 = 207
= 15 + 32n : 4 = 207
= 15 + 8n = 207
= 23n = 207
n = 207/23
n = 9 → Jwbnya

3). 0,002 × 0,015
= 2/1000 × 15/1000
= 1/500 × 3/200
= 3/100000
= 0,00003 → Jwbnya
Atau
= 3. 10^5 → Jwbnya

# Maaf Kalo Salah

12,5 : 0,5 × 7
= 175

15 + (32×n) : 4 = 207
480 + 15n = 207 × 4
15n = 828 - 480
n = 348/15
n = 23,2

0,002 × 0,015 = 0,00003
