3) 0.6 kg ; 3/4 kg ; 400g
4) 1/3 : 2.5 : 3 3/4

Answer 1

Answer:

1) 4 1/5=21/5 , so 21/5kg : 630/1000kg

2100 : 315

20:3

Step-by-step explanation:

2)75/100 : 53/16

12:53

3)600/1000 :750/1000 : 400/1000

12:15:8

4)1/3 : 25/10 : 15/4

now take base(denominator) lcm i.e 60

and multiply with every ratio you will get
