# Q.5 Write each of the following as decimals: (a) $$\frac{5}{10}$$ (b) 3 + $$\frac{7}{10}$$ (c) 200 + 60 + 5 + $$\frac{1}{10}$$ (d) 70 +$$\frac{8}{10}$$ (e) $$\frac{88}{10}$$ (f) $$4\frac{2}{10}$$ (g) $$\frac{3}{2}$$ (h) $$\frac{2}{5}$$ (i) $$\frac{12}{5}$$ (j) $$3\frac{3}{5}$$ (k) $$4\frac{1}{2}$$

(a) $$\frac{5}{10}$$ = 0.5
(b) 3 + $$\frac{7}{10}$$ = 3+ 0.7 = 3.7
(c) 200 + 60 + 5 + $$\frac{1}{10}$$ = 265+ 0.5 = 265.5
(d) 70 +$$\frac{8}{10}$$ = 70+ 0.8 = 70.8
(e) $$\frac{88}{10}$$ = 8.8
(f) $$4\frac{2}{10}$$ = $$\frac{42}{10}$$ = 4.2
(g) $$\frac{3}{2}$$ = $$\frac{3×5}{2×5}$$ = $$\frac{15}{10}$$ = 1.5
(h) $$\frac{2}{5}$$ = $$\frac{2×2}{5×2}$$ = $$\frac{4}{10}$$ = 0.4
(i) $$\frac{12}{5}$$ = $$\frac{12×2}{5×2}$$ = $$\frac{24}{10}$$ = 2.4
(j) $$3\frac{3}{5}$$ = $$\frac{18}{5}$$ = $$\frac{18×2}{5×2}$$= $$\frac{36}{10}$$ = 3.6
(k) $$4\frac{1}{2}$$ = $$\frac{9}{2}$$ = $$\frac{9×5}{2×5}$$ = $$\frac{45}{10}$$ = 4.5
