Polly has a full 5 kg sack of rice.

She pours the rice from this sack into bags.
She fills as many bags as possible.

Each full bag contains 350 g of rice.

How many bags did Polly fill from this sack of rice?

There are a couple of steps involved in solving this problem:

1. Convert the weight of the full sack of rice from kg to g: 5 kg = 5000 g.

2. Divide the weight of the full sack by the weight of each bag to find the number of bags: 5000 g ÷ 350 g/bag = 14.29 bags.

Since Polly can't fill a fraction of a bag, we need to round down to the nearest whole number. Therefore, Polly filled 14 bags from the 5 kg sack of rice.

To find out how many bags Polly filled from the 5 kg sack of rice, we need to convert the weight of the sack of rice from kg to g and then divide it by the weight of each bag.

1 kg = 1000 g

So, 5 kg = 5 * 1000 = 5000 g.

Now, we divide the weight of the sack of rice by the weight of each bag:

Number of bags = 5000 g / 350 g = 14.29

Since we cannot have a fraction of a bag, Polly would have filled a total of 14 bags from the sack of rice.
