Question 252047
Hello, 
We can set up the older child's age as x and the younger would be 1/3(x). Now we can set up an equation like this:
x + 1/3(x)= 16  Multiply by 3 to get rid of the fraction:
3x + x = 48 Combine like terms to  result in:
4x=48 Divide both sides by 4 will give us:
x=12 years old is the older child.
Can you figure the younger child's age now?
