8.3% since 8.3 times 12 equals 100 you would multiply by 1 and that would make it the percent.

Answer:
Step-by-step explanation:
A ratio compares two quantities in terms of multiplication. For example, suppose that there are 10 boys and 15 girls in a classroom. One way, not using ratios, to compare these quantities would be to say that there are 5 more girls than boys in the classroom. To employ a ratio, we say that the ratio of boys to girls is 10 to 15, or 2 to 3. In other words, for every 2 boys in the classroom, there are 3 girls.
In your case, for every 40 boys, there are 20 girls. if we simplify this all the way down, we can get 2 to 1.
All of the following are ratios that apply to your question:
40 to 20
20 to 10
10 to 5
4 to 2
2 to 1

Answer:
Set up a proportion ,
80/x 9/100
9 is over 100 because it is a percent and 100% is the highest %.
doing a proportion you cross multiply getting you..
9x =80 x 100
9x= 800
divide by 9 on both sides
that determines your answer
you try !
Step-by-step explanation:
It would be positive one. Go up one over four then down one over four.
Answer:
A and C
Step-by-step explanation:
A) 160 + 20 = 180
B) 120 + 40 = 160
C) 45 + 135 = 180
D) 30 + 120 = 150
All supplementary angles must add up to 180 degrees.
