Answer 1

Jawaban

1. c. 24

2. c. kelereng Arman = 80. Kelereng budi = 100

Pembahasan

1. A = 20

A/B = 5/6

20/B = 5/6

20/B × 6B = 5/6 × 6B

20 × 6 = 5B

B = 120/5

B = 24

2. A + B = 180

A/B = 4/5

A = 4B/5

4B/5 + B = 180

9B/5 × 5/9 = 180 × 5/9

B = 100

A + B = 180

A + 100 = 180

A = 180 -100

A = 80
