Answer:

Amy's 10 years old

Step-by-step explanation:

Clarence is ⅗ Amy's age

Isaiah is ½ Amy's age

Amy's age = ?

But summation of their age = 21

Clarence + Isaiah + Amy = 21

Let a represents Amy's age

⅗a + ½a + a = 21

Solve for a by resolving the fraction,

2.1a = 21

Divide both sides by 2.1

a = 10

Amy's 10 years old
