Question

a)2+1/3
b)1/2+1/3+1/4
c)2+2/3+3/4
d)1.1/2+3.1/4

Answer 1

a)
$2 + \frac{1}{3} \\ \frac{2}{1} + \frac{1}{3} \\ \frac{2 \times 3}{2 \times 1} + \frac{1}{3} \\ \frac{2 \times 3}{3} + \frac{1}{3} \\ \frac{6}{3} + \frac{1}{3} \\ \frac{6 + 1}{3} \\ \frac{7}{3} \\ 2 \frac{1}{3}$

b)
$\frac{1}{2} + \frac{1}{3} + \frac{1}{4} \\ \frac{1 \times 6}{2 \times 6} + \frac{1 \times 4}{3 \times 4} + \frac{1 \times 3}{4 \times 3} \\ \frac{6}{12} + \frac{4}{12} + \frac{3}{12} \\ \frac{6 + 4 + 3}{12} \\ \frac{13}{12} \\ 1 \frac{1}{12}$

c)
$2 + \frac{2}{3} \\ \frac{24 + 8 + 9}{12} \\ \frac{41}{12}$

d)
$1 \times \frac{1}{2} + 3 \times \frac{1}{4} \\ \frac{1}{2} + 3 \times \frac{1}{4} \\ \frac{1}{2} + \frac{3}{4} \\ \frac{5}{4}$
