1)18/7 :3/15 = 2)20/12 : 21/18= 3)14/5 : 5/3= 3)20/15 : 5/20 Tolong jawab dengan caranya ya

1) 18/7 : 3/15 = 18/7 x 15/3 = 270/21
2) 20/12 : 21/18 = 20/12 x 8/21 = 160/252
3) 14/5 : 5/3 = 14/5 x 3/5 = 42/25
4) 20/15 : 5/20 = 20/15 x 20/5 = 400/75

1)
18/7 : 3/15
= 18/7 . 15/3
= 18/7 . 5/1
= 90/7
= 12 6/7

2)
20/12 : 21/18
= 20/12 . 18/21
= 5/3 . 6/7
= 30/21
= 10/7
= 1 3/7

3)
14/5 : 5/3
= 14/5 . 3/5
= 42/25
= 1 17/25

4)
20/15 : 2/20
= 20/15 . 20/2
= 4/3 . 10/1
= 40/3
= 13 1/3


Moga membantu...
