Worth Comparing Inwards Math

Comparison is called a comparable comparing if ii comparisons are equal.

Formula of Worth Comparison

Example of Worth Comparison

The ratio of the length as well as width of a edifice is 3 : 2. If it is 8m wide, delight specify the length of the building!

Answer:
a = 3
b = 2
a₁ = width
b₁ = 8m

So the length of the edifice is 12m.

Comparison Turns Value Inwards Math

A comparing is called a reversed ratio if ii toll comparisons are reversed.

Formula of comparing turns value

Example:
H5N1 chore tin dismiss survive completed past times 3 workers for 15 days. Determine the worker's banter to survive added for operate to survive completed inside 5 days!

Answer:
a = iii people
b = x
a₁ = xv days
b₁ = v days

So the worker that needs to survive added is 9 - iii = half-dozen workers.

Scale Inwards Math

Scale is a comparable cast of the size of a existent magnitude. The symbol to declare the scale is ":". For representative the scale on the map is written 1: 1,000,000 important if on the map 1cm, together with thence the actual distance is 1,000,000 cm or 10km.

Example interrogation of scale

Distance of 2 cities on the 7.5 cm map. If the scale on the map is 1: 150,000, what is the actual distance ??

Answer:
Actual distance = 7.5 cm x 150,000
Actual distance = 1,125,000 cm
Actual distance = 11.25 km

So the existent distance is 11.25 km.

Operation On Logarithms

1. Multiplication Operations on Logarithms

Formula:

log(a 10 b) = log a + log b

Example:
Count 6.28 10 2.536!

Answer:
If p = 6.28 10 2.536
log p = log (6.28 10 2.536)
log p = log 6.28 + log 2.536
log p = 1.2021
so, p = Antilog 1.2021 = 15.926

2. Division Operations on Logarithms

Formula:

Example:
Count 325.6 : 48.5!

Answer:
If p = 325.6 : 48.5
log p = log (325.6 : 48.5)
log p = log 325.6 - log 48.5
log p = 2.5127 - 1.6857
log p = 0.8270

so, p = antilog 0.8270 = 6,7

3. Root as well as Rank Operations on Logarithms

Formula:

Example:
Using the logarithm table, delight specify the value of:

Answer:
a. if p = 5^8
log p = log 5^8
log p = 8 10 log 5
log p = 8 10 0.6990
log p = 5.592

So, p = antilog 5.592 = 390800

So, p = anti log 0.2553 = 1.8001

Look For Anti Logarithm Alongside Anti Logarithm List

Anti logarithm is the inverse procedure of calculating the value of logarithm. Anti logarithms tin sack hold upwards formed alongside a listing of Anti Logarithms.

Example:
Please elevate one's hear the value of 10 from log 10 = 1.3783 using the antilogaritm tabular array !

Answer:
The release 1 inward 1.3783 is the index, the sediment on 378 is the mantisenya. The figures are listed on the antilogarithm listing on business 37 as well as column 8 inward the next table:

So if log 10 = 1.3783 hence x = 23,9.
