Problem 1 Add 1/16 in and  3/8 in Procedure Set up the problem 1/16 in +  3/8 in = ________ Adjust for common denominators 1/16 + 3/8 = 1/16 + 6/16 = 7/16 Complete the addition 1/16 +  3/8 = 7/16 Solution 1/16 in +  3/8 in = 7/16 in

 Problem 2 Add 2 3/4"  and  1 5/16" Procedure Set up the problem 2 3/4" + 1 5/16" = _____ Add the whole-number parts ( 2 + 3/4 ) + (1 + 5/16) = 3 + 3/4 + 5/16 Adjust the fractions for common denominator 3 + 3/4 + 5/16 = 3 + 12/16 + 5/16 Add the fractions 3 + 12/16 + 5/16 = 3 + 17/16 Simplify 3 + 17/16 = 3 + 1 1/16 = 4 1/16 Solution 2 3/4" + 1 5/16" = 4 1/16"

 Problem 3 Subtract 1/4 in from 3/8 in Procedure Set up the problem 3/8 in –  1/4 in = ________ Adjust for common denominators 3/8 –  1/4 = 3/8 –  2/8 Complete the subtraction 3/8 –  2/8  = 1/8 Solution 3/8 in –  1/4 in = 1/8 in

 Problem 4 Subtract 1 3/16" from 2 1/2" Procedure Set up the problem 2 1/2" –  1 3/16" = ________ " Subtract the whole numbers ( 2 +  1/2 ) – (1 +  3/16 )=  1 + 1/2 –  3/16 Adjust for common denominators 1 + 1/2 –  3/16 = 1 + 8/16 –  3/16 Complete the subtraction 1 + 8/16 –  3/16  = 1 5/16 Solution  1/2" –  1 3/16" =  1 5/16"
