My apologies for the previous incorrect response. Let's calculate the correct answer.
JoJo had 1 1/2 cups of sugar, and she used 3/4 cup for her cookies.
To find out how much sugar she has left, we need to subtract the amount she used from the initial amount she had.
1 1/2 cups - 3/4 cup = (2/2 + 1/2) cups - 3/4 cup = 3/2 cups - 3/4 cup
Now, let's subtract the fractions:
3/2 cups - 3/4 cup = 6/4 cups - 3/4 cup = 3/4 cup
Therefore, JoJo has 3/4 cup of sugar left.

To find the sum of -1/4 and -3/5, we need to find a common denominator for the two fractions.
The common denominator for 4 and 5 is 20.
Converting both fractions to have a denominator of 20:
-1/4 can be written as -5/20. (multiply the numerator and denominator by 5)
-3/5 can be written as -12/20. (multiply the numerator and denominator by 4)
Now, we can add the two fractions:
-5/20 + -12/20 = -17/20
Therefore, -1/4 + -3/5 equals -17/20.

The temperature dropped 9 degrees, so to find the new temperature, we need to subtract 9 from the original temperature of 5°F.
5°F - 9°F = -4°F.
Therefore, the new temperature is -4°F.
