Connie is putting the ingredients for her favorite oatmeal into a jar. The jar holds 2 1/2 cups of ingredients. So far she has added 1 2/3 cups of oats to the jar and 14 cup of raisins. How much room does Connie have left in the jar?

1 answer

To find out how much room is left in the jar, we need to add up the amount of ingredients Connie has added.

Connie has added 1 2/3 cups of oats, which is equal to 5/3 cups.
Connie has also added 14 cup of raisins.

To find the total amount of ingredients added, we add 5/3 and 14:
5/3 + 14 = 43/3 = 14 1/3

Therefore, Connie has added 14 1/3 cups of ingredients to the jar so far.

Since the jar holds 2 1/2 cups of ingredients, we can subtract the amount Connie has added from the total capacity of the jar:
2 1/2 - 14 1/3 = 13/2 - 43/3
To subtract fractions, we need to find a common denominator. The common denominator of 2 and 3 is 6.
13/2 = 39/6 and 43/3 = 86/6
39/6 - 86/6 = -47/6

Therefore, Connie has -47/6 cups of room left in the jar. This means she has used more space in the jar than it can hold, so she needs a bigger jar.
