(b) $$\frac{8}{15} + \frac{3}{15}$$
(c) $$\frac{7}{7} - \frac{5}{7}$$
(d) $$\frac{1}{22}+ \frac{21}{22}$$
(e) $$\frac{12}{15} - \frac{7}{15}$$
(f) $$\frac{5}{8} + \frac{3}{8}$$
(g) $$1 - \frac{2}{3} \Big( 1 = \frac{3}{3}\Big)$$
(h) $$\frac{1}{4} + \frac{0}{4}$$

Answer 1

(a) $$\frac{1}{18} + \frac{1}{18} = \frac{1 + 1}{18} = \frac{2}{18} = \frac{1}{9}$$ (b) $$\frac{8}{15} + \frac{3}{15} = \frac{8 + 3}{15} = \frac{11}{5}$$
(c) $$\frac{7}{7} - \frac{5}{7} = \frac{7 - 5}{7} = \frac{2}{7}$$ (d) $$\frac{1}{22}+ \frac{21}{22} = \frac{1 + 21}{22} = \frac{22}{22} = 1$$
(e) $$\frac{12}{15} - \frac{7}{15} = \frac{12 - 7}{15} = \frac{5}{15} = \frac{1}{3}$$ (f) $$\frac{5}{8} + \frac{3}{8} = \frac{5 + 3}{8} = \frac{8}{8} = 1$$
(g) $$1 - \frac{2}{3} \Big( 1 = \frac{3}{3}\Big) = 1 - \frac{2}{3} = \frac{3}{3} - \frac{2}{3} = \frac{3 - 2}{3} = \frac{1}{3}$$
(h) $$\frac{1}{4} + \frac{0}{4} = \frac{1}{4} + 0 = \frac{1}{4}$$
