Answer:
4/7
Step-by-step explanation:
Number of Blue vans = 4
Number of white vans = 3
Total number of vans = Number of Blue vans + Number of white vans
= 4 + 3

Number of blue vans : Number of white vans = 4 : 3
Fraction of vans that are blue = Number of Blue vans / Total number of vans
= 4 / 7
Fraction of vans that are blue = 4/7
