Concepts and Skills

Question 4.
Use Tools Megan colors $$\frac{5}{6}$$ of her sheet of paper. Natasha colors $$\frac{2}{6}$$ of her paper. The sheets of paper are the same size and shape. Who colors more of her paper? How do you know? Tell what strategy or tool you will use to answer the question, explain your choice, and then find the answer.
Megan colors more of her paper.

Explanation:
Megan colors $$\frac{5}{6}$$ of her sheet of paper
Natasha colors $$\frac{2}{6}$$ of her paper
The sheets of paper are the same size and shape
As the denominators in both the fractions are same, Compare the numerators
5 > 2
So, Megan colors more of her paper than Natasha.

Question 5.
Doug and Maria each have a waffle. The waffles are the same size and shape. Doug eats $$\frac{2}{3}$$ of his waffle. Maria eats $$\frac{5}{6}$$ of her waffle. Who has more waffle left? Explain. Explanation:
Doug and Maria each have a waffle
The waffles are the same size and shape
Doug eats $$\frac{2}{3}$$ of his waffle
Maria eats $$\frac{5}{6}$$ of her waffle
I shaded the fraction in the above shapes
Here the fraction $$\frac{2}{3}$$ has larger missing piece
So, Doug has more waffle left.

Question 6.
Paula and Joey each have equal-sized tortillas. Paula cuts her tortilla into 8 equal pieces and eats 5 of them. Joey cuts her tortilla into 6 equal pieces and eats 5 of them. Who eats less? Explain how you found your answer. Use a drawing to help show your answer.  Explanation:
Paula and Joey each have equal-sized tortillas
Paula cuts her tortilla into 8 equal pieces and eats 5 of them
Joey cuts her tortilla into 6 equal pieces and eats 5 of them.
From the drawing above the fraction that has the larger missing part is smaller
So, Paula has larger missing part
Therefore, Paula eats less when compared to Joey.

Question 7.
What fraction does the number line show?  Explanation:
The number lines hows the fraction $$\frac{3}{4}$$.

Label the fraction $$\frac{3}{8}$$ on the number line.  Explanation:
I labeled the fraction $$\frac{3}{8}$$ on the number line by labeling all the fractions between 0 and 1 with $$\frac{1}{8}$$ as interval.

Write <, >, or = to compare the fractions on the number lines.  Here $$\frac{3}{4}$$ has smaller denominator than the other fraction
Therefore, $$\frac{3}{4}$$ is greater than $$\frac{3}{8}$$.
