For that you need the logarithm table
Write the scale of the drawing as a fraction. Put the shorter length in the numerator.

First convert the denominator to the same units as the numerator. Write an equivalent fraction with centimeters in the denominator. Since 1 meter is equal to 100 centimeters, multiply the denominator by 100 to get centimeters in the denominator.

Write the scale factor as a ratio, using a colon
7/100 → 7:100
The scale factor is 7:100.

<span>So we wan't to know from which number can we take 30% and get 6. Well, lets turn that into an equation. Lets say that x is the number we are looking for. So, 30% of x is equal 6 or mathematically: 30% * x = 6. Now: (30/100)*x=6 and when we multiply both sides with 100 and divide both sides with 30 we get: x=(6*100)/30 and that is equal to: x=20. So 30% out of 20 is 6. </span>
