Step-by-step explanation:
= 3 4/7
= (3 × 7 + 4)/7
= (21 + 4)/7
= 25/7
---
= 6 3/5
= (6 × 5 + 3)/5
= (30 + 3)/5
= 33/5
= 12 2/7
= (12 × 7 + 2)/7
= (84 + 2)/7
= 86/7
So:
= (3 4/7 + 6 3/5) + 12 2/7
= (25/7 + 33/5) + 86/7
= (125/35 + 231/35) + 86/7
= 356/35 + 86/7
= 356/35 + (86 × 5)/(7 × 5)
= 356/35 + 430/35
= 786/35
