Danica and Vincent each buy a pie. Both pies are the same size. Danica eats 2 fourths

of her pie and Vincent eats 4 eighths of his pie.

Draw two number lines to help you compare the amount they ate. Remember to draw both number lines the same length.

Who eats more pie? Write a complete sentence to explain how you know.

Answer explanation

Draw a fraction bar (or 2 equal fraction bars) and shade in 5 fourths.

What does it mean when the numerator (top number) of a fractions is bigger than the denominator (bottom number). *Hint: Think about fractions that represent one whole. How do those look? Now, think about what it would mean if the top number of your fraction was a larger number than the bottom number of your fraction. Think about how you drew the fractions bars in the last question.

Which fraction does not equal 2 wholes, 4 halves or two halves? Write a complete sentence to explain how you know.

Look at the image above. Explain why the greater than and less than signs were chosen for each fraction comparison. For example: "The first pair of fractions compares 2 fourths and 2 eighths. 2 fourths is greater than 2 eighths because the 2 fourths fraction bar is more shaded than the 2 eighths fraction bar. So the alligator mouth is eating the bigger fraction which is 2 fourths." Now, write your own sentences to explain the other two comparisons. Don't be lazy. Spend your time thinking and writing detailed explanations. Re-read your writing to make sure it makes sense. If it doesn't, re-write your sentence.

A storm damaged many lettuce plants this month. In complete sentences, explain what will happen to the price of lettuce. Will there be a high supply of lettuce or a low supply of lettuce? Will this cause the price of lettuce to be higher or lower? Why do you think that?
