This exercise asks you to round each number to the nearest ten.

The rule for rounding to the nearest ten is:

If the ones digit is 5 or greater (5, 6, 7, 8, 9), round up to the next multiple of ten.
If the ones digit is less than 5 (0, 1, 2, 3, 4), round down to the current multiple of ten.

Solve .
The number is 9114. The ones digit is 4.
Since 4 is less than 5, round down.
$9114 \leftarrow \downarrow \rightarrow \boxed{\text{9110}}$
Solve .
The number is 423. The ones digit is 3.
Since 3 is less than 5, round down.
$423 \leftarrow \downarrow \rightarrow \boxed{\text{420}}$
Solve .
The number is 567. The ones digit is 7.
Since 7 is 5 or greater, round up.
$567 \leftarrow \downarrow \rightarrow \boxed{\text{570}}$
Solve .
The number is 666. The ones digit is 6.
Since 6 is 5 or greater, round up.
$666 \leftarrow \downarrow \rightarrow \boxed{\text{670}}$
Solve .
The number is 789. The ones digit is 9.
Since 9 is 5 or greater, round up.
$789 \leftarrow \downarrow \rightarrow \boxed{\text{790}}$
Solve .
The number is 142. The ones digit is 2.
Since 2 is less than 5, round down.
$142 \leftarrow \downarrow \rightarrow \boxed{\text{140}}$
Solve .
The number is 719. The ones digit is 9.
Since 9 is 5 or greater, round up.
$719 \leftarrow \downarrow \rightarrow \boxed{\text{720}}$
Solve .
The number is 222. The ones digit is 2.
Since 2 is less than 5, round down.
$222 \leftarrow \downarrow \rightarrow \boxed{\text{220}}$
Solve .
The number is 286. The ones digit is 6.
Since 6 is 5 or greater, round up.
$286 \leftarrow \downarrow \rightarrow \boxed{\text{290}}$
Solve .
The number is 620. The ones digit is 0.
Since 0 is less than 5, round down (it's already a multiple of ten).
$620 \leftarrow \downarrow \rightarrow \boxed{\text{620}}$
