Write in order of their size of the first circle; of the second circle, and of the third circle. A unit is any one thing. A fraction is one or more of the equal parts of a unit. 22. Write in figures one half; one fourth. How many figures are needed to express a common fraction? In the fraction what does the 4 show? the 3? 23. Read ; ; ; ; ; ; 12. 24. Write seven eighths; thirteen twenty-fourths. The denominator of a fraction, which is written below the line, shows into how many equal parts the unit is divided. The numerator of a fraction, which is written above the line, shows how many equal parts of the fraction are taken. The terms of a fraction are the numerator and denominator. Fractions are said to be equivalent when they have the same value. Thus, 4, and are equivalent fractions. Fractional equivalents of thirds, sixths, and ninths. 1.
