25% is equal to 1/4 or .25 of a whole.
If you do 10 divided by .25 you get 40.
10 is 25% of 40.
Yes.
For example, the LCM of 12 and 36 is 36, because factoring these numbers gives
12 = 2^2 * 3
36 = 2^2 * 3^2
So, to match them, just multiply the twelve by 3, then they're both 36.
it’s system of substitutions ?
so try
a = 2
b = 5
Circumference of a circle = 2πr
Circumference of the whole circle= 2π(30) = 60π
360 - 90 = 270
Length XPY = 270/360 x 60π = 45π
Answer: 45π m
