Answer:
21 grapes.
Step-by-step explanation:
We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.
First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.
[tex]\text{Grapes eaten by Tyrell}=2\times 6[/tex]
[tex]\text{Grapes eaten by Tyrell}=12[/tex]
Now, we will find half of 6 to find number of grapes eaten by Lucy.
[tex]\text{Grapes eaten by Lucy}=\frac{6}{2}[/tex]
[tex]\text{Grapes eaten by Lucy}=3[/tex]
[tex]\text{Grapes eaten by them in all}=6+12+3[/tex]
[tex]\text{Grapes eaten by them in all}=21[/tex]
Therefore, the three of them eat 21 grapes in all.
