1. The answer 0.12 represents the portion of how-to books in the school library that deal with both carpentry and electronics.
2. The number of apples picked that were sold as fresh fruit is 90 (200 - 110 = 90).
3. The total area of Oak Manor is 15.96 square miles (3.8 miles * 4.2 miles = 15.96 mi^2).
4. The height of the basketball player's son is 8 feet (623 / 14 = 44.5 ft).
5. The diver's elevation when he is 23% of the way down is -22.356 feet (-97.2 ft * 0.23 = -22.356 ft).
6. The expression that CANNOT be used to find the diver's depth after 5 minutes is -8 - 8 - 8 - 8 - 8.
7. The price of the kayak at the end of four months is $318 ($378 - (4 * $15) = $318).
A basketball player is 6 2/3
feet tall. His infant son is 1/4
as tall. How tall is his son?
To find the height of the basketball player's son, we need to multiply the height of the basketball player by 1/4.
The basketball player's height is 6 2/3 feet, which is equivalent to 20/3 feet.
So, to find the height of his son, we multiply 20/3 feet by 1/4:
(20/3) * (1/4)
To multiply fractions, we multiply the numerators together and the denominators together:
(20 * 1) / (3 * 4)
The result is:
20/12
Simplifying the fraction, we have:
(10/6) or (5/3)
Therefore, the son's height is 5/3 feet or approximately 1 and 2/3 feet.

To find the diver's elevation when he is 2/3 of the way down, we need to multiply the total depth (97.2 feet) by 2/3.
97.2 feet * 2/3
To multiply fractions, we multiply the numerators together and the denominators together:
(97.2 * 2) / 3
The result is:
194.4 / 3
To simplify the fraction, we divide the numerator by the denominator:
64.8
Therefore, the diver's elevation when he is 2/3 of the way down is -64.8 feet.
