If Ratios the ratio of girls to boys in a room is 1 9 if there are 4 girls How many boys should there be?
Ok, if there is one girl to every nine boys, there are 10 kids in all. that means that if there are 2 girls, you have to double 9, making 18, adding up to 20. . so, 2 girls and 18 boys. If there are 4 girls, then multiply 9 times 4. 4x1 and 4x9. and then you get your answer.

There 5 times as many girls as boys there are 20 boys at the club how many girls are there?
5g = 1b (5 girls for every 1 boy) Xg = 20b (unknown number of girls for every 20 boys.) It looks like the answer is as easy as multiplying 20 by 5, which equals 100. Why? Well if you actually had a bunch of girls and boys together, you would get 20 boys and ask that 5 girls go to each boy. Then imagine in your head how many girls there are around the 20 boys, even if you have to draw a picture.
