Answer
$322_{\text{five}}$
Work Step by Step
The place values of base five are: $,,,, 5^3, 5^2, 5^1, 1$.
The place values that are less than or equal to $87$ are $5^2$, $5^1$, and $1$
Divide $87$ by $5^2$ or $25$ to obtain:
$87 \div 25 = 3$ remainder $12$
Divide the remainder $12$ by $5^1$ or $5$ to obtain:
$12 \div 5 = 2$ remainder $2$
Divide the remainder $2$ by $1$ to obtain:
$2 \div 1 = 2$ remainder $0$
Thus,
$87=(3 \times 5^2) + (2 \times 5^1) + (2 \times 1)
\\87=322_{\text{five}}$
