Question

Lesley's fruit salad contains 40% grapes. Which figure represents 40%?
A hundredths model with 50 squares shaded blue.
A hundredths model with 28 squares shaded blue.
A hundredths model with 30 squares shaded blue.

Answer 1

40% = 40/100, so on a hundredths (100-square) grid you need 40 squares shaded. None of the given figures show 40 squares shaded (50, 28, and 30 squares are 50%, 28%, and 30% respectively).
