tolong ya kakak soal ini gmn caranya. 8/10=...% 5/20=...% 3/4=...% .terimakasih

Answer 1

8/10 = 8/10 × 10/10 = 80/100 = 80%
5/20 = 5/20 × 5/5 = 25/100 = 25%
3/4 = 3/4 × 25/25 = 75/100 = 75%

Answer 2

8/10= 8/10÷100 = 8/10 × 1/100= 8/1000
= 0,008 %

5/20=5/20÷100= 5/20×1/100= 5/2000 = 0,025 %

3/4= 3/4÷100 = 3/4×1/100= 3/400 = 0,0075 %
