In this section, we learn how to compare the relative size of two or more fractions. We will learn two different methods:

• Convert each fraction into an equivalent fraction with the LCD (56) as the Denominator $$\frac{21}{56}\hspace{.25em}or\hspace{.25em}\frac{16}{56}$$ • 21 is larger than 16 $$\frac{3}{8} > \frac{2}{7}$$ Cross Multiply

• Multiply: 7 x 7 = 49

• 66 is the larger product, the numerator 6 belongs to the larger fraction $$\frac{7}{11} < \frac{6}{7}$$

- Convert each Fraction into an Equivalent Fraction with the LCD as the Denominator
- Cross Multiply

- Identify the LCD for the denominators of the fractions involved
- Convert each fraction into an equivalent fraction with the LCD as the Denominator
- Compare numerators, the larger numerator belongs to the larger fraction

• Convert each fraction into an equivalent fraction with the LCD (56) as the Denominator $$\frac{21}{56}\hspace{.25em}or\hspace{.25em}\frac{16}{56}$$ • 21 is larger than 16 $$\frac{3}{8} > \frac{2}{7}$$ Cross Multiply

- Multiply the denominator of one fraction by the numerator of the other
- The numerator from the larger product belongs to the larger fraction

• Multiply: 7 x 7 = 49

• 66 is the larger product, the numerator 6 belongs to the larger fraction $$\frac{7}{11} < \frac{6}{7}$$
