Butterfly method
10x5 is 50
50 divided by 2 is 25

Answer 2

25 in.

Explanation:

Since we know geckos are 2/5 of an Iguana's length, we need to find the length of 1/5.

So if 10 in. is 2/5, 5 in, is 1/5.

Now, since the denominator is 5, we multiply 5 in. by 5.

5x5=25 in.

25 in. is the length of an average Iguana.
