Answer:
The longest insect is 5/8 inches longer than the shortest.
To find how much longer the longest insect is than the shortest, we have to subtract the length of the shortest insect from the longest one.
The shortest insect is 1/8 inches
The longest insect is 3/4 inches
So, we have to do 3/4 - 1/8
To do that, we have to find a common denominator
A denominator is the bottom number of a fraction
A common denominator between 3/4 and 1/8 is 8
We can write 3/4 as 6/8 because they are equal
Now we do 6/8 - 1/8
6/8 - 1/8 = 5/8
5/8
