Transform the ratios into fractions. You can do this one of two ways, each leading to the same correct answer. I'll do it the following way:
5x/2x = 2x/16 Since x/x = 1, eliminate the x's as follows:
5/2 = x/8 Having reduced the right side. Multiply both sides by 8.
40/2 = x
20 = x Now check the answer as follows:
5x/2x = 2x/16
5(20)/2(20) = 2(20)/16
100/40 = 40/16
5/2=5/2

5x over 2x=2x over16
Simplifying:
5/2 = x/8
2x = 5.8
x = 40/2
x = 20

5x/2x = 2x/16
simplify first makes it easier
5/2=x/8
cross multiply
2x=40
x=20
Check it if you want
5x/2x = 2x/16
5(20)/2(20) = 2(20)/16
100/40 = 40/16
5/2 = 5/2
x=20

First you're able to flow the 9 to the different area you are attempting this by way of multiplying the two factors by way of 9. then you definately get..... m = (24/36)*(9/a million) = 216/36 m= 216/36 then you definately shrink the fraction by way of applying branch...... m = 216/36 = 108/18 = fifty 4/9 = 18/3 = 6/a million m = 6

5x/2x= 2x/16
5x(16)= 2x(2x) Cross multiplication
80x=4xsq.
4xsq.-80x=0
too hard to do on compute.. sry..
now do the diamond problem, and figure out the 2 factors
best of luck
