No statement provided, so I could help you in a general way. Here we know that Wanda has eaten 25 of the 28 grapes. In other words, we can define this as follows:
[tex]\text{Total number of grapes}=28 \\ \\ \text{Number of grapes she ate}=25[/tex]
So we can write this as a percentage form as follows:
[tex]\% \ \text{Grapes eaten}=\frac{25}{28}\times 100 = 89.28\%[/tex]
So an statement that is true is that Wanda has eaten almost 90% of the grapes.
