Final answer:
Jenny measured a total of 13/30 cup of flour after adding 1/10 cup and 1/3 cup together. The answer is simplified, and it does not match any of the provided multiple-choice options.
Step-by-step explanation:
To solve how many total cups of flour Jenny measured, we need to add the two amounts together: 1/10 cup and 1/3 cup. To do this, we need a common denominator, which in this case is 30. Thus, we convert 1/10 cup to 3/30 cups and 1/3 cup to 10/30 cups, and then add them together:
3/30 cup + 10/30 cup = 13/30 cup.
However, the answer needs to be in reduced terms. We can simplify 13/30 by looking for any common factors but find that it is already in its simplest form. So, Jenny measured a total of 13/30 cup of flour.
Looking at the multiple-choice options, none of them match this simplified fraction, suggesting there might be a typo in the options provided. The correct answer isn't listed within the provided options.
