A baker uses 70 grams of sea salt for each batch of bread. Sea salt comes in a 42-kilogram package or a 1,500-gram package. Which size package should the baker buy so that no sea salt is left after all of the batches are made? Explain.

Baker should use 18-kilogram pack so that no salt is left in the end.

Step-by-step explanation:

In order to find which bag should he buy, we have to check for which bag the 30 grams salt can be taken out completely i.e. which quantity is divided by 30 grams completely.

If a quantity is not divided by 30 completely that means that there will be salt left.

so,

For 800-grams pack:

Salt for one batch of bread = 30-grams
