When you are asked to round off a number, you

must determine whether the additional digit

(which is to be dropped) is 5 or more.*

If

5 1/8 6 2/7 =

this additional digit is 5 or more, you must

add 1 to the last digit that will remain in

41/8 44/7 =

the answer; if this additional digit is 4 or

less, the last digit remains unchanged.

41/8 x 7/44 =

For example:

a.

.7787 (round

off

to

three

(3)

decimal

places)

Answer: .779. Since 7 is more than 4, 1

is added to 8 to make 9.

b.

.7897 (round

off

to

three

(3)

decimal

places)

Answer: .790. Since 7 is more than 4, 1

is added to 9 to make 10 and the 1 is

carried over to the next digit, 8, to make

9.

c.

.7443 (round

off

to

three

(3)

decimal

places)

Answer: .744. Since the 3 is less than 5,

the last digit, 4, will remain unchanged.

*"Rounding-Off" of decimals - remember, even

though you must work out problems to the

highest number of places any element in the

problem contains, your answer may be accurate

only to the degree of accuracy of your meter.

If your meter will measure only to one tenth

or one hundredth then your answer with five or

six figures to the right of the decimal would

not be measurable, and the answer should be

rounded off.
