Share £45 in the ratio 4:5

Calculate 2⁵

let the 2 persons that are sharing be:

person 1 under 4, x 

person 2 under 5, y

so we have:

\(person1:person2:sum\)

\(4:5:9\)

\(x:y:25\)

\(y=(5*25)/9\)

y=\(13.888888888888888888889\)

\(x=(4*25)/9\)

x=11.1111111111111111111111

Approx. is good in this case so,

y=14

x=11 

In a ratio of 4:5 means there are 9 parts to be shared(4+5)

one would be 4/9   of 45 = 20

    the other would be 5/9 *45 = 25
