9 Problem-Attic format version c EducAide Software Licensed for use by Cherise Matechak Terms of Use at 03/3/ ; The second shape Response clearly shows two different ways to divide the figure into fourths. The two wholes have different areas, and are thus different sizes. In order to correctly compare these two fractions, we need to draw a picture of them with the same sized whole. The picture below correctly shows that 2 is greater than 4. False; True; False; True; False Emily s answer of 2 6 would mean that all six little boxes are the whole and two of these have been shaded: For Raj, there are 3 small boxes in the whole so the two shaded boxes represent two out of three or 2 3 : For Alejandra, each little box is one and so the whole is one little box as pictured below: ; ; 4 ; The areas are different. Rectangle F and Rectangle G are not the same whole. 0. Yes ( = 3 3 = ) ; No ( 34 = 2 = 4 3 ) ( ; No 34 2 = 6).
