Answer:
Andy is 4 years old.
Step-by-step explanation:
Given:
Ruth age = 10
We need to find Andy age.
Let the age of Andy be x.
Also given Andy is two-fifths of Ruth's age.
Expressing the above statement in expression form we get
[tex]x= \frac{2}{5}\times Ruth's\ age= \frac{2}{5}\times 10 = 4[/tex]
Hence Andy is 4 years old.
