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: 2:1
4:2
8:4
10:5
20:10
Step-by-step explanation:
For every 2 boys there is one girl which keeps it even.
For every 4 boys there would be 2 girls which keeps it even.
For every 8 boys there would be 4 girls which keeps it even and not having less of anybody or more of anybody and so forth.
