If 3/4 of a rectangle is shaded, what fraction of the rectangle is shaded?

If 3/4 of a rectangle is shaded, what fraction of the rectangle is shaded?

• A. 3/5
• B. 2/3
• C. 1/4
• D. 3/4

Answer: (D)

Understanding fractions of a whole means the shaded portion is described by the same fraction that represents how much of the whole is shaded. If three of the four equal parts are shaded, that shaded portion is three out of four parts, written as 3/4. So the fraction of the rectangle that is shaded is 3/4. The other fractions describe different splits of the whole: 3/5 would mean three parts shaded out of five, 2/3 would mean two parts shaded out of three, and 1/4 would mean one part shaded out of four. None of those match the description of three out of four parts being shaded, so they aren’t correct here.
