Ajapanese beetle has length between 0.3 and 0.5 inches. find two lengths that are within the given span. write them as fraction in simplest form? ps no one has done it !

A Japanese beetle’s length are equals to
=> 0.3 inches
=> 0.5 inches

Now let’s find the length that is between the span of the two given length:
But before that let’s convert the 2 given numbers in decimal points to fraction:
=> 0.3 = 3/10
=> 0.5 = 5/10

Find the fraction between the given 2 numbers:
=> 0.3
=> 0.4
=> 0.5

Therefore the number we are looking 0.4
=> 0.4 = 4/10
Now, we have the complete length of Japanese beetles, the 0.3, 0.4 and 0.5

Where's the rest of the
