Given that x : 3 : 9/2 = 15/4 : 4 1/2 : y, find the value of x and y.

x = , y =

Step-by-step explanation:

Equate the first 2 parts of the ratios on both sides of the equation and solve for x.

Expressing the ratios in fractional form, then

= = × = ( cross- multiply )

6x = 15 ( divide both sides by 6 )

x = =

-----------------------------------------------------------------------------------

Equate the last 2 parts of the ratios on both sides and solve for y

= = 3 × = ( cross- multiply )

2y = × 3 = ( divide both sides by 2 )

y =

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
