Answer: 3

SOLUTION 1 :

Simplify.

$\frac{1}{7}$		$\frac{16}{60}$
		↓
$\frac{1}{7}$		$\frac{8}{30}$

Use a common denominator

$\frac{1}{7}$		$\frac{8}{30}$
↓		↓
$\frac{30}{210}$		$\frac{56}{210}$

$\frac{1}{7}$ is less than $\frac{16}{60}$ , So:

$\frac{1}{7}$ < $\frac{16}{60}$

Which sign makes the statement true

$\frac{-41}{81}$ 0

1) ' title=">"/> >
2) <
