Studdy Solution

STEP 1

What is this asking? If we have 18 snakes and put 2 snakes in each tank, how many tanks do we need? Watch out! Don't mix up the number of snakes per tank with the total number of snakes!

STEP 2

1. Figure out what operation to use
2. Set up the expression

STEP 3

We're splitting the **18** snakes into groups of **2**.
This sounds like division!
We want to find out how many groups of **2** fit into **18**.

STEP 4

We're dividing the **total number of snakes**, which is 1818, by the **number of snakes per tank**, which is 22.

STEP 5

So, our expression is 18÷218 \div 2.
We're dividing the **total** by the **size of each group** to find the **number of groups** (tanks).

STEP 6

The correct answer is (A) 18÷218 \div 2.
