Question

Express the ratio 3 1
/2


hours : 14 minutes in the form k : 1.​

Answer 1

Step-by-step explanation:

first take 3 1/2 hrs=7/2 hrs

convert hrs to min

1 hr=60 min

7/2 hrs=7/2*60=210 min

3 1/2hours=210 min

so substitute in question

3 1/2hours : 14 minutes=210:14

divide by 14 on both

3 1/2hours : 14 minutes=15:1
