The picture above represents pieces of metal weighed and stamped by authority of government, and used in buying and selling. Such pieces of metal are coins. Each coin represents a unit of value. 127. Dollars and cents are the units of value chiefly used in business. Eagles, dimes, and mills are also used, but there is no coin to represent a mill. = 1 eagle. TABLE. = 1 cent, marked ct. or . = 1 dime. = 1 dollar, marked $. To read and write numbers in United States Money. 128. The dollar, being the principal unit of United States money, is expressed at the left of the decimal point; dimes, cents, and mills, being tenths, hundredths, and thousandths of a dollar, are expressed at the right of the decimal point. Thus, 11 dollars, 2 dimes, 3 cents, and 4 mills are written $11.234; and the expression is read, "Eleven dollars twenty-three cents four mills." For exercises in reading and writing, turn to page 73. 129. Oral Exercises in Reduction. a. How many mills in 1 cent? in 18 cents 5 mills? By what do you multiply to change cents to mills? dollars to cents? dollars to mills? b. Change $14.08 to cents. c. Change $1.62 to cents. e. Change $2.625 to mills. 1. Change $5.02 to mills. g.

In performing the examples above, you have changed numbers expressing a certain amount of money to numbers whose units are larger or smaller, but without changing the amount itself. Such a process is called reduction. For other examples in reduction of United States money, see page 73. 131. Examples for the Slate. ADDITION, SUBTRACTION, MULTIPLICATION, AND DIVISION.
