Total = 300
Smokers = 234
Non-smokers = 300 - 234 = 66
Percentage of smokers = 66/300 x 100 = 22%
--------------------------------------------------------------
Answer: 22% of the people smoke.
--------------------------------------------------------------
8 White
6 Black
4 Blue
5 Brown
Total=8+6+4+5=23
1. White to brown = 8:5
2. Blue to non-blue =4:(23-4) = 4:19
3. Black to all = 6 : 23
4. Ratios equivalent to Q1, 8:5
Multiply ratio by integer factors:
2(8:5)=16:10
3(8:5)=24:15
4(8:5)=32:20
etc.
Hey!
When you're dividing fractions, you have to keep, change, flip
Keep 3/4
Change ÷ to ×
Flip 1/8 = 8/1
That gives you:
<em>That means your answer is the 2nd choice</em>
Good luck and hope this helps! :)
