In examples 4-13 change the given complex fractions to simplest 14. If of an acre of land is worth $72-3, what is the value. of 3 acres at the same rate? 15. There are 5 yards in a rod. How many rods in 1401 yards? 16. At $6 a ton how many tons of coal can be bought for $778? 136. In division, if the divisor contains a common fraction that cannot easily be reduced to a decimal, it is sometimes helpful to multiply both dividend and divisor by the denominator of the fraction, thus making both dividend and divisor integers, or simple decimals; e.g.: .0211).416 Multiplying both dividend and divisor by 3, and then dividing, Written 19.5 Quotient .064)1.248.0 137. In the following examples find the quotients correct to two COMPARATIVE STUDY OF DECIMALS AND COMMON FRACTIONS 138. A fraction that is expressed by writing the numerator above and the denominator below a line is a common fraction; e.g., . (See § 9 for definition of decimal fractions.) 49 All decimal fractions may be expressed as common fractions without reducing them; e.g. .010411846. What common fractions can be expressed as decimals without reducing them? 139. When a decimal fraction is expressed without its denominator, by using the decimal point, it is said to be expressed in the decimal form. In like manner tell the meanings of the following decimals: 140. A decimal may be reduced to a common fraction in simplest form by expressing it as a common fraction and reducing lowest terms: e.g. .8585617; 13.8138 = 13; 50 1 1 to = 100 163/ 141. Written. Reduce the following decimals to common fractions or mixed numbers in simplest form : 142. Since a fraction is an expression of division, a common fraction may be reduced to a decimal by dividing its numerator by its denominator. Before dividing, place a decimal point after the dividend. Annex ciphers as they are needed; e.g. 144. A fraction in lowest terms whose denominator contains other prime factors than 2 and 5 cannot be reduced to an exact |
