9 5/10 -- 1/23 = 43546 = 92146≅ 9.456522
Calculation steps
Conversion a mixed number to a improper fraction: 9 5/10 = 9 · 10 + 510= 9510
Subtract: 9510 - 123 = 95 · 2310 · 23 - 1 · 1023 · 10 = 2185230 - 10230 = 2185 - 10230 = 2175230 = 43546
The common denominator you can calculate as the least common multiple of the both denominators - LCM(10, 23) = 230
For this case we first write the equation of which we will use:
I (db) = 10log (l / l)
We substitute the value of l.
We have then:
l = 10 ^ 8lo
Substituting in the given equation:
I (db) = 10log ((10 ^ 8lo) / lo)
Rewriting:
I (db) = 10 * log (10 ^ 8)
I (db) = 80
Answer:
I (db) = 80
