Jawaban:

1. 1,140

2. 1

3. 13,25 kg

Penjelasan dengan langkah-langkah:

1. 0,75 = 75/100

20 % = 20/100

1,2 = 12 /10

( 75/100 + 20 /100) = 95/100 × 12/10

= 1140/1000

= 1,140

2. 75% = 75/100

0,8 = 8/10

0,6 = 6/10

75/100 × 8/10 = 600/1000 ÷ 6/10 = 600/1000 × 10/6 = 6000/6000 = 1

3. 20/100 × 13.5 = 2,7 kg

13.5 – 2,7 = 10.8 kg + 2,45 kg = 13,25 kg

semoga membantu
