Answer:
b) f = 11 2/7
Explanation:
Now we have to,
→ Find the required value of f.
The equation is,
→ 3 + f = 14 2/7
Then the value of f will be,
→ 3 + f = 14 2/7
Converting mixed fraction to proper:
→ 3 + f = ((14 × 7) + 2)/7
→ 3 + f = (98 + 2)/7
→ 3 + f = 100/7
Subtract the Right hand side with 3:
→ f = (100/7) - 3
→ f = (100/7) - (21/7)
→ f = (100 - 21)/7
→ f = 79/7
Converting proper fraction to mixed:
→ f = (77 + 2)/7
→ f = (77/7) + (2/7)
→ [ f = 11 2/7 ]
Hence, the value of f is 11 2/7.
