1. 45 % : 0.25 X 2 1/ 4 = …

Jawab:

1. 4,05 / 405% / 4 1/20

2. 1,5 / 1 1/2

3. 21/10 / 2,1 / 2 1/10

4. 36/25 / 1 9/25

5. 3/50

Penjelasan dengan langkah-langkah:

1. 45 % = 45/100

0,25 = 25/100

2 1/4 = 9/4

45/100 : 25/100 x 9/4 = 45/100 x 100/25 x 9/4 = 45/1 x 1/25 x 9/4 = 405/100 = 4,05 / 405% / 4 1/2

2. 1/2 = 1/2

2,25 = 225/100, dibagi 25 jadi = 9/4

3/4 = 3/4

1/2 x 9/4 : 3/4 = 1/2 x 9/4 x 4/3 = 36/24, dibagi 12 jadi = 3/2 atau 1 1/2

3. 15 % = 15/100, dibagi 5 = 3/20

3,5 = 35/10, dibagi 5 jadi = 7/2

4/1 = 4

3/20 x 7/2 x 4/1 = 84/40, dibagi 4 jadi = 21/10 = 2,1 / 2 1/10

4. 1 4/5 = 9/5

0,25 = 25/100 = 1/4

1/5 = 1/5

9/5 : 1/4 x 1/5 = 9/5 x 4/1 x 1/5 = 36/25 / 1 9/25

5. 0,75 = 75/100, dibagi 25 jadi = 3/4

0,2 = 2/10, dibagi 2 jadi = 1/5

2 1/2 = 5/2

3/4 x 1/5 : 5/2 = 3/4 x 1/5 x 2/5 = 6/100, dibagi 2 jadi = 3/50

maaf ya kalau salah 🙂
