Question

Joe has fraction 5 over 6 pound of bird seed. He needs Fraction 1 over 3. pound to feed the birds daily. Which of the rectangle models below shows how many days’ worth of seed Joe has left?

A. Rectangle model divided into six equal sections, five sections are labeled five-sixths and three sections are labeled one-third, equaling one and two-thirds days.
B. Rectangle model divided into six equal sections, five sections are labeled five-sixths and two sections are labeled one-third, equaling two and one-half days.
C. Rectangle model divided into three equal sections, three sections are labeled five-sixths and one section is labeled one-third, equaling three days.
D. Rectangle model divided into six equal sections, five sections are labeled five-sixths and one section is labeled one-third, equaling five days.

Answer 1

A. Rectangle model divided into six equal sections, five sections are labeled five-sixths and three sections are labeled one-third, equaling one and two-thirds days.

Explanation:

Answer 2

I divided the two fractions & drew a model.


`(5)/(6)/ (1)/(3) = 2.5`

So we know that the bird seed will last 2.5 days.

Knowing this, we can go with:

B. Rectangle model divided into six equal sections, five sections are labeled five-sixths and two sections are labeled one-third, equaling two and one-half days.
