Question

Round off the following numbers to the nearest integer:
(a) $288.29$ (b) $3998.37$ (c) $4856.795$ (d) $4999.96$

Answer 1

(a) $288.29\simeq 288$ (b) $3998.37\simeq 3998$
(Here, the tenth place in the above numbers are less than $5$. Therefore all the integers are left as they are.)
(c) $4856.795\simeq 4857$ (d) $4999.96\simeq 5000$
[Here, the tenth place in the above numbers are greater than $5$. Therefore the integer values are increased by $1$ in each case.]
