Question

Answer 1

a: =4/7+1/7+2/7+3/4+5/4

=1+2

=3

b: =5/2+7/2+6/11+5/11+3/8+6/8

=6+1+9/8

=7+9/8

=65/8

c: =4/3+7/3+1/3+3/5+2/5

=4+1

=5

Answer 2

\(\Rightarrow A=\left(\dfrac{4}{7}+\dfrac{2}{7}+\dfrac{1}{7}\right)+\left(\dfrac{3}{4}+\dfrac{5}{4}\right)\\ A=1+2\\ A=3\\ B=\left(\dfrac{5}{2}+\dfrac{7}{2}\right)+\left(\dfrac{6}{11}+\dfrac{5}{11}\right)+\left(\dfrac{3}{8}+\dfrac{6}{8}\right)\\ B=6+1+\dfrac{9}{8}\\ B=7+\dfrac{9}{8}\\ B=\dfrac{56}{8}+\dfrac{9}{8}=\dfrac{64}{8}\)
