3:4
The ratio is: 3 to 4
The ratio is: 2 to 1
ratio is 1:2 in other words for every 1 boy there are 2 girls
The ratio is 4:5
I'm guessing u ment that the ratio was 4:3 so you do 35 divided by 7 (4+3) = 5 4 times 5 =20 (boys) 3 times 5 = 15 (girls) so there are 5 less girls than boys

Andd thee answeer is......20 girls and i don't want 2 explain =)
To find the number of boys in Mandy's school, we first need to express the ratio of boys to girls (1720) in a simplified form. The ratio can be interpreted as 17 boys for every 20 students (17 boys + 3 girls = 20 students). To find the number of boys, we can set up the equation: ( \text{Total students} = \text{boys} + \text{girls} ). Let ( x ) represent the number of boys; then ( x + \frac{3}{17}x = 1300 ). Solving this gives us approximately 780 boys in the school.
First add 8 and 9 to get 17. Then divide 340 by 17 to get 20. Then times 20 by 8 to find the number of girls or times 20 by 9 to get the number of boys. Number of girls: 160 Number of boys: 180
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%
It is 1.566... repeating metres.
15/20=3/4
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.
