dengan caranya tapi pakai bilangan desimal
jawab yang benar​

Answer 1

21,7 : 0,7

= 217/10 : 7/10

= 217/10 × 10/7

= 217/1 × 1/7

= 217/7

= 31

7,2 : 1,2

= 72/10 : 12/10

= 72/10 × 10/12

= 72/1 × 1/12

= 72/12

= 6

6,4 : 0,16

= 64/10 : 16/100

= 64/10 × 100/16

= 64/1 × 10/16

= 640/16

= 40
