    How to round any digit?

    To round up or down tens place then we need to look at the unit place if it is less than 5 then we need to keep it as it and if it is greater than 5 then we need to round up the tens digit.
    Given the product,
    281 x 2.16
    Round to nearest hundred of 281 →
    Since 81 > 50 so it will round up as 300
    Rounding to the nearest whole number of 2.16
    Since 16 < 50 so it will round down as 2
    Therefore,
    281 x 2.16 ⇒ 300 × 2
    Hence “The best approximation of product  281 x 2.16 is 300 x 2″
