Write one measurement that is between 3/16 inche and 7/8 inche on a ruler

Well, one end of that space is  3/16, and the other end is  7/8.

But  7/8  is exactly the same as  14/16 .

So inside that space you'll find any number of sixteenths,
from  3  of them all the way to  14  of them.

If you're good at handling fractions, you'll find that all of
these measurements are in there too:

1/2
1/4, 3/4
3/8, 5,8
all the thirty-seconds, from  7/32  to  27/32
all the sixty-fourths, from  13/64  to  55/64 .

Like the oregano in the spaghetti sauce, they're IN THERE !
