The man is 27 years old and the son is 9 years old.
We can write the son's age as 'x', and therefore write the man's age as 4x. In 3 years, both their ages will increase by 3, so the son's age is now x + 3, and the man's age is 4x + 3.
We are told that the man is now 3 times older than his son, which means his current age, 4x + 3, is the same as 3 times the son's current age, which is x + 3.
Therefore we can write an equation:
4x + 3 = 3(x + 3)
4x + 3 = 3x + 9
- 3x
x + 3 = 9
- 3
x = 6
We can now substitute this in to find their current ages:
Son's age = x + 3 = 6 + 3 = 9
Man's age = 4x + 3 = 24 + 3 = 27

Answer:
1. C 2. B
Step-by-step explanation:
1. 0.75 is equivalent to 3/4.
We can put this in mixed number form to get 6 3/4.
2. When I was in sixth grade, my teacher taught me a trick to form a number into an improper fraction.

Multiply the whole number by the denominator, then add the numerator. Then, put that number over the denominator.
47/8. That is B.
Hope it helped!
