X = 1st. number, 3X = 2Nd number.

3X*X = 9 18/25

3X^2 = 9 18/25 = 243/25

X^2 = 243/75 = 81/25

X = sqrt(81/25) = 9/5 = 1 4/5 = 1st number

3X = 3 * 9/5 = 27/5 = 5 2/5 = 2Nd

number.

Data:

let x and y are two possative numbers

xy = 9 18/25 = 243/25

x = 3y

calculate

x = ?

y = ?

Solution

xy = 243/25

3y.y = 243/25

3y2 = 243/25

divide 3 to both side

y2 = 81/25

square root to both side

y = 9/5

for x

x = 3y

x = 3.9/5

x = 27/5

hence two positive number are 9/5 and 27/5
