Problems from Rounding and truncating decimal numbers

Round and truncate these three numbers to hundredths.

$a = 2, 654$

$b = 13, \hat{187}$

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

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:

$a = 2, 65$

$b = 13, 18$

$c = 19, 13$
