pecahan desimal dan persen

tentukan pecahan desimal dari pecahan biasa berikut ini (beserta caranya)

1. 4/5 =

2. 3/8 =

3. 15/25 =

persen

1. 29/50 =

2. 37/50 =

3. 2/5 =

4. 1/4 =

5. 11/20 =​

Penjelasan dengan langkah-langkah:

desimal

1. 4/5 = 4×2/5×2 = 8/10 = 0,8

2. 3/8 = 3×125/8×125 = 375/1000 = 0,375

3. 15/25 = 15×4/25×4 = 60/100 = 60÷10/100÷100 = 6/10 = 0,6

persen

1. 29/50 = 29×2/50×2 = 58/100 = 58%

2. 37/50 = 37×2/50×2 = 74/100 = 74%

3. 2/5 = 2×20/5×20 = 40/100 = 40%

4. 1/4 = 1×25/4×25 = 25/100 = 25%

5. 11/20 = 11×5/20×5 = 55/100 = 55%
