B) 1 2/3
C) 3 2/5
D) 5 1/2
E) 7 1/3
F) 4 1/6
​

Answer 1

$1 + \frac{2}{7} = \frac{7}{7} + \frac{2}{7} = \frac{9}{7} \\ \\ 1 + \frac{2}{3} = \frac{3}{3} + \frac{2}{3} = \frac{5}{3} \\ \\ 3 + \frac{2}{5} = \frac{15}{5} + \frac{2}{5} = \frac{17}{5} \\ \\ 5 + \frac{1}{2} = \frac{10}{2} + \frac{1}{2} = \frac{11}{2} \\ \\ 7 + \frac{1}{3} = \frac{21}{3} + \frac{1}{3} = \frac{22}{3} \\ \\ 4 + \frac{1}{6} = \frac{24}{6} + \frac{1}{6} = \frac{25}{6}$

Answer 2

Oie, Td Bom?!

a)

$1 \frac{2}{7} = \frac{1 \times 7 + 2}{7} = \frac{7 + 2}{7} = \frac{9}{7}$

b)

$1 \frac{2}{3} = \frac{1 \times 3 + 2}{3} = \frac{3 + 2}{3} = \frac{5}{3}$

c)

$3 \frac{2}{5} = \frac{3 \times 5 + 2}{5} = \frac{15 + 2}{5} = \frac{17}{5}$

d)

$5 \frac{1}{2} = \frac{5 \times 2 + 1}{2} = \frac{10 + 1}{2} = \frac{11}{2}$

e)

$7 \frac{1}{3} = \frac{7 \times 3 + 1}{3} = \frac{21 + 1}{3} = \frac{22}{3}$

f)

$4 \frac{1}{6} = \frac{4 \times 6 + 1}{6} = \frac{24 + 1}{6} = \frac{25}{6}$
