Change .8 to sixteeths inches

Answer 1

.8 equals 8/10 which is slightly larger then 3/4. (3/4 - 7.5/10)

3/4 equals 12/16, so .8 is slightly larger than 12/16, so call it 13/16 which is close enough if you are doing carpentry.

If you need more accuracy, set it up like this:

8 / 10 = ? / 16 (where ? is unknown)

Use cross-multiplication to solve for the unknown:

8 x 16 = 10 x ?

128 = 10 x ?

128 / 10 = ?

12.8 = ?

So 8 / 10 = 12.8 / 16

which is pretty close to what we guessed, 13/16.

Answer 2

To convert 0.8 inches to sixteenths of an inch, you multiply by 16 since there are 16 sixteenths in an inch. 0.8 inches is equal to 12.8 sixteenths of an inch (0.8 x 16 = 12.8).
