Complete question :
Joyce uses 3/10 bag of chocolate chips for each batch of cookies she makes. What is the least number of batches Joyce can make if she has to open a second bag of chocolate chips? Enter your answer in the box.
Answer:
4 batches
Explanation:
Fraction of a bag of chocolate used per batch = 3/10 of a bag
Least number of batches that must be made if a second bag must be open :
Number of batches that can be made from the first bag :
1 bag / (3/10 of a bag)
1 / (3/10 * 1)
1 / (3/10)
1 ÷ (3/10)
1 * 10/3 = 10/3
= 3.333 batches
If another bag will be open, the it will be used to complete the incomplete batch. Hence, the least number of batches that can be made will be 4
