iii) 7:1

iv) 28:15

Answer 2

Step-by-step explanation:

i) 28:49

= 28/49

= 4:9

ii) 4 ml to 1 litre 200 ml

=> 1 l = 1000 ml

=> 1 l 200 ml = 1000+200 ml

= 1200 ml

Now, 4:1200

= 4/1200

= 1:300

iii) 2 weeks to 2 days

=> 1 week = 7 days

=> 2 weeks = 7×2 = 14 days

Now, 14:2

=14/2

=7:1

iv) 4 hours to 75 minutes

=> 1 hr = 60 mins

=> 4 hrs = 4×60 = 240 mins

Now, 240:75

= 240/75

= 16:5
