it is the way how we take it out

for example

Answer:

Answer => (C)20&30

Step-by-step explanation:

Ok so Her it is,

Let the ratios be 2x and 3x respectively,

so,

\frac{2x+5}{3x+5} = \frac{5}{7}

3x+5

2x+5

so,

7(2x+5) = 5(3x+5)

14x + 35 = 15x + 25

14x - 15x = 25 - 35

-x = -10

x = 10

then thde numbers are 20 & 30 respectively..

In mathematics, a root of unity, occasionally called a de Moivre number, is any complex number that yields 1 when raised to some positive integer power n. ... Any algebraically closed field contains exactly n nth roots of unity, except if n is a multiple of the (positive) characteristic of the field.!
