Mariana [72]

Answer:

Bucket 2

Step-by-step explanation:

Bucket 1 = 4700ml

Bucket 2 = 4.8l

Bucket 3 = 3880ml

Bucket 4 = 4.71 l

Convert holding capacity of bucket 1 and bucket 3 into liters

1 liter = 1000 milliliter

Bucket 1 = 4700ml

4700ml = 4.7l

Bucket 3 = 3880ml

3880ml = 3.88l

Therefore,

Bucket 1 = 4.7l

Bucket 2 = 4.8l

Bucket 3 = 3.88l

Bucket 4 = 4.71 l

The bucket closest to 5liters is bucket 2 with a holding capacity of 4.8 liters
