1. dik : x1 = 50 orang
y1 = 75 orang

x2 = 60 hari
y2 = ..... hari


2. dik : x1 = 100 km/jam
y1 = 80 km/ jam

x2 = 8 jam
y2 = ..... jam


3. dik : x1 = 75 ekor
y1 = 25 ekor

x2 = 50 hari
y2 = ..... hari​

Jawaban:

1. 40 hari

2. 10 jam

3. 150 ekor

Penjelasan dengan langkah-langkah:

1. x1/y2 = x2/y2

50/75 = 60/y2

y2 = 50/75 × 60

y2 = 50/5 × 4

y2 = 200/5

y2 = 40

2. x1/y1 = x2/y2

100/80 = 8/y2

y2 = 100/80 × 8

y2 = 100/10 × 1

y2 = 100/10

y2 = 10

3. x1/y1 = x2/y2

75/25 = 50/y2

y2 = 75/25 × 50

y2 = 75/1 × 2

y2 = 75 × 2

y2 = 150
