Answer:
d) 4.
Step-by-step explanation:
Let Santiago be x years old today.
Then Juan is x + 8 years old.
In 4 years Santiago will be x + 4 years.
In 4 years Juan will be x + 12 years.
From the given information:
x + 4 = 0.5(x + 12)
x = 0.5x + 6 - 4
0.5x = 2
x = 2 / 0.5
x = 4.
To solve this proportion, cross multiply.
By cross multiplying, you will multiply 2.75 * (2/9) and 9 * x.
0.61 = 9x
Divide both sides by 9.
x = 0.067... which rounds to 0.068, so your answer is:
D) x 
0.068
