Round $294$ to the nearest ten.

Hint: While rounding a number to nearest tens place we should consider the number in the ones place and analyze it. There are different processes performed depending on the nature of the number present in the one's place i.e. considering if it greater than or lesser than the number 5. So based on the above statement we can perform the same steps for the number given and then round it to the nearest ten.

Complete step-by-step solution:
Given
\[294....................................\left( i \right)\]
Now from (i) we can see that in the given number we have 9 in tens place and 4 in the ones place.
Now while rounding a number to the nearest ten we have to consider the number present in the ones place such that:
a) If the number in the ones place is greater than 5 then it’s rounded up such that to the next nearest ten considering the number in the tens place.
b) If the number in the ones place is lesser than 5 then it’s rounded down such that to the same value of ten considering the number in the tens place.
So here in the tens place we have 9 which can either be rounded up or down.
Here at ones place we have 4 which is less than 5 so the number$294$is rounded down such that it’s rounded to the nearest lowest ten which would be 90.
Therefore on rounding $294$we can write:
$294 = 290$.

Note: On solving questions similar to the above one we should always take care about the two rules mentioned above such that it would be easier to execute the simplification process. Rounding of a number simply means the process of replacing it with another number such that it’s nearly equal and can be represented in a much easier way.
