• 3/4 + 2/4 = 1 2/4

• 4/4 + 3/4 = 7/4

• 3/4 + 2/4 = 5/4

What equation is shown on the number line?

• 3/6 + 4/6 = 1 1/6

• 3/6 + 4/6 = 8/6

• 4/6 + 5/6 = 1 1/6

• 4/6 + 5/6 = 9/6

Which equation is shown on the number line?

• 3/4 + 1/4 = 4/4

• 3/2 + 1/2 = 4/2

• 1 1/2 + 1/2 = 3/2

What is the difference between Ethan's and Zniyah's miles that they ran?

• 3 Miles

• 2 4/8 Miles

• 8/8 Miles

• 8/8 + 8/8 Miles

What equation represents Nelson and Bobby's combined miles that they ran?

• 4 7/8 - 3 4/8 = 1 3/8

• 5 5/8 + 4 7/8 = 9 12/8

• 5 5/8 + 4 7/8 = 10 2/8

• 5 5/8 - 4 7/8 = 1 2/8

Can you find the difference in miles from Ethan and Bobby?

• Yes, because 6 4/8 - 4 7/8 equals 2 3/8.

• No, because you can't subtract 6 4/8 from 4 7/8, because 4/8 is less than 7/8.

• Yes, because even though you can't subtract 6 4/8 from 4 7/8, you can take 1 from the 6 and then add that to 4/8, making it 5 12/8. So, 5 12/8 - 4 7/8 = 1 5/8.

• Yes, because even though you can't subtract 6 4/8 from 4 7/8, you can just subtract the whole numbers so 6 - 4 = 2, and then you do 7/8 - 4/8 and you have 3/ 8, the answer is 2 3/8.

• 5/2 - 2/2 = 3/4

Ms. Lovins had 7/4 cup of cat food for her cat. Her cat ate 4/4 by the end of the week. Which equations BEST describes the model?

• 7/4 - 4/4 = 3/8

• 1 3/4 - 1 = 3/4

• 1 3/4 - 1 = 2 3/4

• 7/4 - 1 = 3/8
