Answer:
Cross Multiply
Step-by-step explanation:
1. Multiply 16 by 9 and you get 144
2. Multiply 5 by x
This is called cross multiplying.
3. Set up the equation. 5x=144
144/5=28.8
x=28.8
To get the answer we can use proportion
86 --------------45%
x ---------------- 100%
Now cross multiply
x*45%=86*100
45x=8600 /:45 (divide both sides by 45)
x=191.11 - its the answer
