Problems from Rounding and truncating decimal numbers

Round and truncate these three numbers to hundredths.

$$a=2,654$$

$$b=13,\widehat{187}$$

$$c=19,13\widehat{76}$$

See development and solution

Development:

Rounding:

$$a=2,65$$

$$b=13,19$$

$$c=19,14$$

Truncating:

$$a=2,65$$

$$b=13,18$$

$$c=19,13$$

Solution:

Rounding:

$$a=2,65$$

$$b=13,19$$

$$c=19,14$$

Truncating:

$$a=2,65$$

$$b=13,18$$

$$c=19,13$$
