Find the upper bound for the following lengths: a) 14.2 cm correct to 1 decimal place.
b) 43.18 cm correct to 2 decimal places.

Step-by-step explanation:

To round up numbers to 1 decimal place we consider the second number  after the decimal point, if this number is 5 or above we round the previous number one place upward, else we leave the number the way it is

i.e 14.20 cm to 1 decimal place is 14.2 because the next number "0" is not up "to 5"

To round up numbers to 2 decimal place we consider the third number  after the decimal point, if this number is 5 or above we round the previous number one place upward

i.e 43.180 cm  to 2 decimal place is 43.18 because the next number "0" is not up "to 5"
