Step 1: Simplify each fraction.
56
6 and 5 have no common factors other than 1, so 56 is simplified.
84=8÷44÷4=21
123=12÷33÷3=41
Step 2: Add the simplified fractions 56+21+41.
The least common denominator (LCD) of 5, 2, and 4 is 20.
56=5×46×4=2024
21=2×101×10=2010
41=4×51×5=205
Step 3: Add the fractions.
2024+2010+205=2024+10+5=2039
