There are 7/8 cups of sugar in a canister in the kitchen. Ms. Johnson used 1/2 of the sugar when she was preparing dessert for her daughter's birthday cake. How much sugar did she use?(1 point)
To find out how much sugar Ms. Johnson used, we need to multiply the 7/8 cups of sugar by 1/2.
7/8 * 1/2 = (7 * 1) / (8 * 2) = 7/16 cups
Therefore, Ms. Johnson used 7/16 cups of sugar.
One-third of the campers at Rosewood Performing Arts Camp play an instrument. Two-fifths of those campers play the guitar. What fraction of the campers at Rosewood Performing Arts Camp play the guitar?(1 point)
To find the fraction of campers who play the guitar, we need to multiply the fraction of campers who play an instrument (1/3) by the fraction of those campers who play the guitar (2/5).
(1/3) * (2/5) = 2/15
Therefore, 2/15 of the campers at Rosewood Performing Arts Camp play the guitar.

To calculate the number of apples that were sold as fresh fruit, we need to find the quantity of apples that Sara discarded and subtract that from the total number of apples she picked.
She discarded 1/10 of the 200 apples, which is calculated as:
1/10 * 200 = 20 apples discarded
The number of apples sold as fresh fruit is:
200 - 20 = 180 apples
Therefore, 180 apples were sold as fresh fruit.

To calculate the total area of Oak Manor, we need to multiply the length (3.8 miles) by the width (4.2 miles).
Area = length x width
Area = 3.8 miles * 4.2 miles
Area = 15.96 square miles
Therefore, the total area of Oak Manor is 15.96 mi^2.
