Sara discarded 1/10 of the apples she picked as defective. Of the apples remaining, 300 were made into cider. The rest were sold as fresh fruit. What fraction of the total apples picked were sold as fresh fruit?(1 point)
To find the fraction of the total apples picked that were sold as fresh fruit, we first need to determine how many apples were left after discarding the defective ones.
If Sara discarded 1/10 of the apples, this means 9/10 of the apples remained.
Out of the remaining apples, 300 were made into cider.
So, 9/10 - 300/total apples = fraction of apples sold as fresh fruit.
To determine the fraction, we need to find the common denominator between 10 and the total number of apples. However, without knowing the total number of apples, we cannot calculate the exact fraction.

To calculate the total area of Oak Manor, we need to multiply the length and width of the town.
Accomplishing this:
A = length × width
A = 3.8 miles × 4.2 miles
A = 15.96 square miles
Therefore, the total area of Oak Manor is 15.96 square miles.
A diver searches for a sunken treasure that is 97.2

To find the diver's elevation when he is 2/3 of the way down, we need to multiply the depth of the treasure by 2/3, and then subtract it from the surface level.
Calculating this:
Depth = 97.2 feet
2/3 of the depth = (2/3) * 97.2 = 64.8 feet
Elevation = Surface level - 2/3 of the depth
Elevation = 0 - 64.8 = -64.8 feet
Therefore, the diver's elevation when he is 2/3 of the way down is -64.8 feet.
A basketball player is 6 2/3 feet tall. His infant son is 1/4 as tall. How tall is his son?(1 point)
To find the height of the basketball player's son, we need to multiply the height of the player by 1/4.
Calculating this:
Height of the basketball player = 6 2/3 feet
Height of the son = (6 2/3) * 1/4
To perform the calculation, we first convert the mixed number to an improper fraction:
Height of the player = 6 + 2/3 = (6*3 + 2)/3 = 20/3 feet
Now we can calculate the height of the son:
Height of the son = (20/3) * 1/4 = (20*1)/(3*4) = 20/12 = 5/3 feet
Therefore, the son of the basketball player is 5/3 feet tall.
1) 0.12 makes up the amount of how-to books about electronics.
