MACHINE SHOP CALCULATION - OD1640 - LESSON 1/TASK 2
number 3 to the left of the decimal point is a plain 3, meaning 3 whole
units. The second 3 is three tens or thirty. In reading from the left of a
decimal point, each unit increases in value by ten times the unit to its
right.
FIGURE 7.
DECIMAL PLACES.
What happens to the right of the decimal point? Figure 7 indicates that the
first three to the right of the decimal point is three-tenths of one. The
second three to the right of the decimal point is three-hundredths of one.
In reading to the right of a decimal point, each unit decreases in value by
one-tenth of the unit to its left. Thus, 333. is read three hundred thirty-
three.
If the decimal point is moved one place to the left, it becomes
33.3, or thirty-three and three-tenths.
Again, move the decimal point to
the left one space.
It is now 3.33.
This is read as three and thirty-
three-hundredths.
