Question

A)3/7+4/5=
B)1/3+3/4+1/2=
C)3/10+10/3=
D)1/6+3/4+2/5=

Answer 1

a)
$\frac{3}{7} + \frac{4}{5} = \frac{15}{35} + \frac{28}{35} = \frac{43}{35}$
b)
$\frac{1}{3} + \frac{3}{4} + \frac{1}{2} = \frac{4}{12} + \frac{9}{12} + \frac{6}{12} = \frac{19}{12}$
c)
$\frac{3}{10} + \frac{10}{3} = \frac{9}{30} + \frac{100}{30} = \frac{109}{30}$
d)
$\frac{1}{6} + \frac{3}{4} + \frac{2}{5} = \frac{10}{60} + \frac{45}{60} + \frac{24}{60} = \frac{79}{60}$
