If a Diplodocus ate 5 trees 3 times a day, how many would he eat in two days?

30 trees

Step-by-step explanation:

There's 2 ways to solve this.

1. You know that it eats 5 trees 3 times a day, so you would do 5*3. After you do that you can find out thats 15 trees a day. You can do 15+15 or 15*2 (you get the same answer)

2. You can multiply them all at once since multiplication works that way. 5*3*2

5*3=15

15*2=30

Either way you get 30 trees.
