Question 1128712

Here's the general rule for rounding:

If the number you are rounding is followed by {{{5}}}, {{{6}}}, {{{7}}}, {{{8}}}, or {{{9}}}, round the number {{{up}}}. 
Example: {{{38}}} rounded to the nearest ten is {{{40}}}.

If the number you are rounding is followed by {{{0}}}, {{{1}}}, {{{2}}}, {{{3}}}, or{{{ 4}}}, round the number down. 
Example: {{{33}}} rounded to the nearest ten is {{{30}}}.


you have:

{{{53.2361}}}
{{{87.867682}}}
{{{122.499235}}}
{{{157.130788}}}

first, make sure you round it to whole numbers

{{{53}}}
{{{88}}}
{{{123}}}
{{{157}}}

now apply rules above and round them to  the nearest {{{10}}}

{{{53}}}->{{{50}}}
{{{88}}}->{{{90}}}
{{{123}}}->{{{120}}}
{{{157}}}->{{{160}}}
