Answer:

22 1/8 mm.

Step-by-step explanation:

First add the whole numbers, then the fractions:

3 + 5 + 5 + 7 = 20

7/8 + 7/8 + 3/16 + 3/16    Change the 7/8's to 14/16:

= 14/16 + 14/16 + 3/16 + 3/16

=  28/16 + 6 /16

= 34 /16

= 2 2/16

= 2  1/8

So the final answer is 20 + 2 1/8

= 22 1/8 mm.
