Question 5.
a.
Spectrum Math Grade 3 Chapter 6 Posttest Answer Key 8

Answer: \(\frac{1}{5}\) >\(\frac{2}{5}\)
Explanation: Given the two pentagon figures with fraction values.
Now, we will find the greater fraction value in a given value.
So, the values are \(\frac{1}{5}\),\(\frac{2}{5}\).
i.e., \(\frac{1}{5}\) >\(\frac{2}{5}\).
Therefore, \(\frac{1}{5}\) is greater than \(\frac{2}{5}\).

b.
Spectrum Math Grade 3 Chapter 6 Posttest Answer Key 9

Answer: \(\frac{1}{3}\) <\(\frac{7}{8}\)
Explanation: Given the two circles figures with fraction values.
Now, we will find the lesser fraction value in a given value.
So, the values are \(\frac{1}{3}\),\(\frac{7}{8}\).
i.e., \(\frac{1}{3}\) < \(\frac{7}{8}\).
Therefore, the value \(\frac{1}{3}\) is less than \(\frac{7}{8}\).

c.
Spectrum Math Grade 3 Chapter 6 Posttest Answer Key 10
Answer: \(\frac{4}{8}\) = \(\frac{1}{2}\)
Explanation: Given the two rectangle figures with fraction values.
Now, we will find the greater, lesser, or equal fraction value in a given value.
So, the values are \(\frac{4}{8}\),\(\frac{1}{2}\).
i.e., \(\frac{4}{8}\) =\(\frac{1}{2}\).
Therefore, the value \(\frac{4}{8}\) is equal to \(\frac{1}{2}\).
