Answer:
Tom can either take 24 kicks and make 16 goals or 30 kicks and make 20 goals.
Step-by-step explanation:
Andre made 4 goals out of 6 kicks.
Tom wants to take more than 20 kicks and to make an equivalent fraction to Andre.
<u>Possibility 1:</u>
Let Tom makes 24 kicks.
To get 24, we need to multiply the denominator of Andre's fraction by 4.
So, 
Therefore, Tom can take 24 kicks and make 16 goals.
<u>Possibility 2:</u>
Let Tom makes 30 kicks.
To get 30, we need to multiply the denominator of Andre's fraction by 5.
So, 
Therefore, Tom can take 30 kicks and make 20 goals.
