Nyatakan hasil berikut dalam bentuk persen dari pecahan biasa !

Jawaban:

1. 57% + 7/20 = 57%+35% = 90%

7/20= 0,35×100= 35%

2. 18% + 6/25 = 18%+24% = 42%

6/25= 0,24×100= 24%

3. 30% + 2 9/10 = 30%+145% = 175%

2 9/10= 29/10 = 1,45×100= 145%

4. 46% – 3/20 = 46% – 15% = 31%

3/20= 0,15×100= 15%

5. 9/10- 57% = 90%-57% = 33%

9/10 = 0,9 x100= 90%

6. 8 2/5 -30 % =840 % – 30% = 810%

8 2/5 = 42/5 = 8,4 x 100 = 840%

semoga membantu
