3 and 3/16 + 10/16 = 3 and 13/16
3 and 3/16 + 10/16 = 3 and 13/16
3 and 3/16 + 10/16 = 3 and 13/16
ANSWER: 1 5/8 SOLUTION: 2 hat + -3/8 2 hat times 8 is equal to 16 2 × 8 = 16 16 subtract to 3 is equal to 13 16 -3/8 = 13/8 13 divide 8 is equal to 1 5/8
2X + 6X - 3 = 13 add 2X and 6X together 8X - 3 = 13 add 3 to each side 8X - 3 + 3 = 13 + 3 8X = 16 divide both sides integers by 8 (8/8)X = 16/8 X = 2 ----------------check in original equation 2(2) + 6(2) - 3 = 13 4 + 12 - 3 = 13 13 = 13 checks
2X - 3 = 13 add 3 to each side 2X = 16 divide both sides by 2 X = 8 check 2(8) - 3 = 13 13 = 13 checks

13/16 3+9=12 4+8=12 12 is divisible by 3 39/3=13 48/3=16 13/16 can not both be divided by the same number (13 is a prime number)
1/8 * 6 = 6/481/3 * 16 = 16/4813/16 * 3 = 39/486/48 + 16/48 + 39/48 = 61/4861/48 = 1 13/48
The LCM of 8, 13 and 16 is 208.
