actually larger than the one given. Likewise, the (-) sign is used to show

that the result is actually less than the one given. In other cases, it may

be advisable to round off a decimal to a given value as described in the

rule below.

certain number of places, write the last place as one figure larger if the

next figure to the right is a 5 or larger. Should this figure be less than

5, discard it from the figure.

EXAMPLE

Suppose when solving a problem a result such as 52.56266666 is obtained.

To

write it correctly to three decimal places it is written as 52.563+.

To

write this same number in two decimal places, it is written 52.56+.

12.

Conclusion

This task described the processes for converting fractions to decimals and

decimals to fractions; and adding, subtracting, multiplying, and dividing

decimals for the purpose of helping the machinist to achieve greater

accuracy of measurements involved in his work. Now complete the practical

exercise which is designed to reinforce your learning of the material

presented in the two tasks of this lesson.
