Answer: Yes. Jamie’s claim is reasonable.

Explanation:

Jamie had \(\frac{4}{5}\) of a spool of twine. He then used \(\frac{1}{2}\) of a spool of twine to make friendship knots. So \(\frac{3}{10}\) of the original spool of twine leftover. Since

\(\frac{4}{5}\) –\(\frac{1}{2}\) = \(\frac{8}{10}\) – \(\frac{5}{10}\) = \(\frac{3}{10}\)

He claims to have \(\frac{3}{10}\) of the original spool of twine leftover. So it is equla to what he leftover. So his claim is reasonabale.

Question 20.

Apply Students are voting for a new school mascot. So far, the results show that \(\frac{3}{10}\) of the students voted for “Fightin’ Titan,” \(\frac{1}{2}\) of the students voted for “Nifty Knight,” and the rest of the students have not voted yet. What fraction of the student population has not voted yet?

(A) \(\frac{3}{10}\)

(B) \(\frac{2}{5}\)

(C) \(\frac{1}{5}\)

(D) \(\frac{4}{5}\)

Answer: (C) \(\frac{1}{5}\)

Explanation:

So far, the results show that \(\frac{3}{10}\) of the students voted for “Fightin’ Titan,” \(\frac{1}{2}\) of the students voted for “Nifty Knight,” Then \(\frac{8}{10}\) voted. Since

\(\frac{3}{10}\) +\(\frac{1}{2}\) = \(\frac{8}{10}\)

So \(\frac{1}{5}\) of the students have not voted yet. Since

1- \(\frac{8}{10}\) = \(\frac{1}{5}\)

Question 21.

Explanation:

Tina spent \(\frac{3}{5}\) of her paycheck on a trip to the beach. She spent \(\frac{3}{8}\) of her paycheck on new clothes for the trip. So Tortal Spent is \(\frac{39}{40}\)

\(\frac{3}{5}\) + \(\frac{3}{8}\) = \(\frac{39}{40}\)

(B) \(\frac{1}{2}\)

(C) \(\frac{7}{12}\)

(D) \(\frac{1}{4}\)

Answer: (C) \(\frac{7}{12}\)

Explanation:

\(\frac{1}{6}\) of band practice was spent trying on uniforms. The band spent \(\frac{1}{4}\) of practice on marching. So Total time spent is \(\frac{5}{12}\). So Time left is \(\frac{7}{12}\)

\(\frac{1}{6}\) + \(\frac{1}{4}\) = \(\frac{5}{12}\)

1-\(\frac{5}{12}\) =\(\frac{7}{12}\)
