Answer:
29
Step-by-step explanation:
Let c, r, g stand for the current ages of Carolina, Raul, and Ginny. Then we have the relations ...
c = 2r
g = 3r +4
c + r + g = 52
Substituting for c and g, we get ...
2r + r + (3r +4) = 52
6r = 48 . . . . . . . . . . . . . subtract 4
r = 8 . . . . . . . . . . . . . . . divide by 8
g = 3(8) +4 = 28 . . . . . .Ginny is presently 28
On Ginny's next birthday, she will be 29.
To solve this equation you will need common demoninators. So, find a number that both 3 and 2 can go into. They can both go into 6. Whatevr you do to the denominator, you have to do to the numerator. Since we multiplied 3 times 2 to get 6, we multiply the numerator 2 by 2 as well leaving us with 4/6. Do the same to the other fraction. 2 times 3 is 6, so 1 times 3 is 3. We are left with 4/6 and 3/6. Now we add! 4 + 3 is 7 so as an improper fraction it would be 7/6. As a mixed number and proper fraction it would be 1 1/6. So your answer is approximately 1 1/6.
