Concepts and Skills

Question 1.
When two fractions refer to the same whole, explain why the fraction with a lesser denominator has larger pieces than the fraction with a greater denominator.
Type below:
___________

Answer: If two fractions have the same numerator but different denominators the fraction with greater denominator is smaller.
Example: Let us consider an apple that is divided into equal parts.
If the apple is divided among 2 people.
Then each get \(\frac{1}{2}\) part of the apple.
If the apple is divided among 4 people.
Then each get \(\frac{1}{4}\) part of an apple.
Hence, in the first case, people get more amount of apple than the second.
Hence, if as a whole the denominator is less the fraction is greater.

Question 2.
When two fractions refer to the same whole and have the same denominators, explain why you can compare only the numerators
Type below:
___________

Answer: If the denominators are the same, then the fraction with the greater numerator is the greater fraction. The fraction with the lesser numerator is the lesser fraction.
Example:
Let us consider a pizza which is cut into 4 parts.
One person ate 3 pieces then the fraction is \(\frac{3}{4}\)
And the other person ate 1 piece then the fraction is \(\frac{1}{4}\)
Now compare the fractions \(\frac{1}{4}\) and \(\frac{3}{4}\)
First person ate 2 pieces more than the second person.

Answer: \(\frac{1}{8}\) < \(\frac{1}{6}\)

Explanation:

Jenna painted \(\frac{1}{8}\)of one side of a fence.
Mark painted \(\frac{1}{6}\) of the other side of the same fence.
The numerators of both fractions are the same. So compare the denominators.
\(\frac{1}{8}\) & \(\frac{1}{6}\)
The denominator with the greatest number will be the smallest fraction.
So, \(\frac{1}{8}\) < \(\frac{1}{6}\)

Question 18.
Danielle drew a model to show equivalent fractions.

Use the model to complete the number sentence.
\(\frac{1}{2}\) = \(\frac{□}{□}\) = \(\frac{□}{□}\)
Type below:
___________

Answer: \(\frac{1}{2}\) = \(\frac{2}{4}\) = \(\frac{4}{8}\)

Total number of boxes are 4 and each are grouped into 2 = 8
Out of 4 boxes 2 boxes are shaded = \(\frac{2}{4}\)
\(\frac{2}{4}\) = \(\frac{1}{2}\)
Next out of 8 grouped squares 4 are shaded = \(\frac{4}{8}\)
\(\frac{4}{8}\) = \(\frac{1}{2}\)
Therefore the equivalent fractions are \(\frac{1}{2}\) = \(\frac{2}{4}\) = \(\frac{4}{8}\)

Question 19.
Floyd caught a fish that weighed \(\frac{2}{3}\) pound. Kira caught a fish that weighed \(\frac{7}{8}\) pound. Whose fish weighed more? Explain the strategy you used to solve the problem.
_____

Answer: Kira

Explanation:

We need to find equivalent fractions with the same denominator:
So Make the denominators of \(\frac{2}{3}\) and \(\frac{7}{8}\) equal.
\(\frac{2}{3}\) × \(\frac{8}{8}\) = \(\frac{16}{24}\)
\(\frac{7}{8}\) × \(\frac{3}{3}\) = \(\frac{21}{24}\)
\(\frac{16}{24}\) < \(\frac{21}{24}\)
Therefore \(\frac{2}{3}\) < \(\frac{7}{8}\)

Question 20.
Sam went for a ride on a sailboat. The ride lasted \(\frac{3}{4}\) hour.

What fraction is equivalent to \(\frac{3}{4}\)?
\(\frac{□}{□}\)

Answer: \(\frac{6}{8}\)

Explanation:

Total number of boxes are 4 and each is grouped into 2 = 8
Out of 4 boxes 3 boxes are shaded = \(\frac{3}{4}\)
Next out of 8 grouped squares 6 are shaded = \(\frac{6}{8}\)
Thus the fraction is equivalent to \(\frac{3}{4}\) is \(\frac{6}{8}\)
