Mixed Fraction Addition and Subtraction Problems Solution:
= 5/11 + 41/8

= ((5 × 8) + (41 × 11)) / (11 × 8)

= (40 + 451) / 88

= 491/88

= 491/88

= 5 51/88 Solution:
= 23/9 + 31/3

= ((23 × 3) + (31 × 9)) / (9 × 3)

= (69 + 279) / 27

= 348/27

= 116/9

= 12 8/9

Example 3: Solution:
= 6/5 − 4/8

= ((6 × 8) − (4 × 5)) / (5 × 8)

= (48 – 20) / 40

= 28/40

= 7/10

Example 4: Solution:

= 94/11 − 10/12

= ((94 × 12) − (10 × 11)) / (11 × 12)

= (1128 – 110) / 132

= 1018/132

= 509/66
