Respuesta :

Answer: The answers are (1) D, (2) A, (3) A, (4) B and (5) B.


Step-by-step explanation: The calculations are as follows

(1) Given that, Cathy read one-sixth of her book and on Tuesday, she read two-sixth of her book. So, the total part of the book that she read is

[tex]\dfrac{1}{6}+\dfrac{2}{6}=\dfrac{1+2}{6}=\dfrac{3}{6}=\dfrac{1}{2}.[/tex]

(2) Part of the Pizza left after the party that Jack has is four-eighth and he eats one-eighth part again, then the remaining part of the pizza left is

[tex]\dfrac{4}{8}-\dfrac{1}{8}=\dfrac{4-1}{8}=\dfrac{3}{8}.[/tex]

(3) The total of two-third cups and two-third cups is

[tex]\dfrac{2}{3}+\dfrac{2}{3}=\dfrac{4}{3}=1\dfrac{1}{3}.[/tex]

(4) Seven-eighth inch is longer than five-eighth by

[tex]\dfrac{7}{8}-\dfrac{5}{8}=\dfrac{2}{8}=\dfrac{1}{4}.[/tex]

(5) In our blood, plasma is more than blood cells by

[tex]\dfrac{11}{20}-\dfrac{9}{20}=\dfrac{2}{20}=\dfrac{1}{10}.[/tex]

Thus, the correct options are (1) D, (2) A, (3) A, (4) B and (5) B.
