A class of 25 students includes 12 boys. Does the ratio of girls to students represent a fraction Does the ratio of boys to girls represent a fraction How do you know?
total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25
What is the ratio of 15 boys to 12 girls?
The ratio of 15 boys to 12 girls can be simplified by finding the greatest common divisor of 15 and 12, which is 3. Dividing both numbers by 3 gives us a ratio of 5 boys to 4 girls. This means for every 5 boys, there are 4 girls in the group.
What percentage is girls in a classroom of 12 girls and 18 boys and how did you get the answer?
Total students = Girls (12) plus Boys (18) equal 30 ie Girls (12) divided by total Students (30) = .40 multiply by 100 to get percentages =40 %
There are 27 students in Mr Rodriguez's class The number of boys and girls are both composite numbers There are 3 more girls than boys How many girls and boys are in the class?
12 boys, 15 girls The composite numbers bit is irrelevant. b+g=27 g-b=3 add the equations b+g+g-b=27+3 2g=30 g=15
How do you find the ratio of 9 to 12?
9 to 12 is the ratio. BUT, if you simplify it (divide them both by the same number which makes both of them come out to a whole number) it's 3 to 4
