How many whole numbers are between 1 and 50 that are divisible by 2?
kupik [55]

Answer:

25

Step-by-step explanation:

The first number in the range 1 - 50 that is divisible by 2 is 2 itself.  Then 4, 6, 8, ....

Here's one way to think and count:

2 \rightarrow 1\\4 \rightarrow 2\\6 \rightarrow 3\\8 \rightarrow 4\\\vdots\\50\rightarrow 25

In the table, the number on the right is <u>half</u> the number on the left.  The numbers on the right are just counting numbers (natural numbers), so there are 25 even numbers between 1 and 50.
