There are 54 students in the school, and the number of boys is 125 girls.

The number of boys is 125% of girls, that is, when girls are 100%, boys are 125% of girls, that is, girls are 1, then boys are 5 4, 25% more than girls, and 125% of boys, 100% of girls, a total of 225%, 225% contains 9 25%, so divide 54 by 9=6, know that a 25% is 6, there are 5 boys, and there are 4 girls, then there are 30 boys, and there are 24 girls.

It's easy to do if you understand it.

Boys are times more than girls, if there are 8 girls, there are 10 boys, and it adds up to 18, magnified three times 18 times 3 = 54, so girls have 8 times 3 = 24, boys have...

This is simple: if you set the girls to x, then the boys are 125%x the total number of students is 54, which is the boys + girls = 54, so that is x+125%x=54, and the solution is x is 24, and the girls are 24, and the boys are 125%x and 30.

It's been a long time since I've solved the problem.

Untie; If the number of girls is x, then the number of boys is 125%xx+125%x=54 gives x=30

125%x=24

Answer; The number of male students is:

The amount of more: 125%+1=225%, 225%=54 people.

A: There are 30 boys. There are 24 girls.

There are 1520 students in the whole school, and there are 120 more students in the boys' 3 4 than in the girls' 3 4, so the boys 1 4 are 40 more than the girls 1 4;

There are more blind boys than noisy girls (120 + 40) = 160.

There are = 1360 2 = 680 girls in the whole school

There are = 680 + 160 = 840 boys in the school.

If there are x girls, then (1520-x) multiplied by 3 4 minus x multiplied by 3 4 = 120

The female trembling rolled raw eggplant to lift the remainder.

525 (Trouser Answerer).

Boys have 1025 525 = 500 (people).

A: There are 500 boys and 525 girls.

Let the number of women guessing the number of rock sparrows give birth to jujube yards is x, then.

x+(4/5)x+80=1025

9/5)x=945

x=525 (person).

Male Spike early = 1025-525 = 500 (person).

There are 653 boys in the school, 104 more than girls, then the number of girls is: 653-104=549 (people), when you know what a number is, another is more or less than this number, you need to use subtraction to calculate; The total number of students in the school can be known: 653 + 549 = 1202 (people).

Then, if you ask for the sum of these two numbers, you need to use addition to calculate. This question is a question that examines students' flexible use of addition and subtraction. Using the number of male and female students in the school to solve the problem can make the students have a more tangible feeling and grasp the use of addition and subtraction more easily.

There are 653 boys, 104 more than girls, which means that if there are girls, there are 653 people, plus 104 people, then if there are girls, there are 757 girls, 757 girls, and 653 boys, a total of 1410

First of all, you should calculate this question first, the number of girls is 653-104, and then you can add up the boys and girls.

I think this problem should first take 653 for boys and subtract 104 to get the number of girls, and then add the number of girls and the number of boys to get the total number of students in the school.

There were 653 boys, 104 more than girls, and how many people were in the school, 653 2+104

There are 956 boys in the school, and the number of boys is 138 less than that of girls, so the number of girls is (956 + 138) 2 = 547.

So the total number of boys and girls is 956 plus 547 equals 1503.

The number of girls is 14 13 of the number of boys, so the ratio of girls to boys is 14:13 and girls have 540 divided by 14 27 = 280.

For boys, 540 divided by 13 27 = 260.

A: There are 260 boys and 280 girls.

If the number of boys is x, then the number of girls is 14 13x

Column equation x+14 13x=540

The solution is x=280

So it's 280 for boys and 260 for girls

Don't ask such a simple question.

Let the boy be x, then the girl is 13 14x, according to the meaning of the problem, the Lalie equation is obtained: x+13 14x=540 solution: x=280, that is, the boy has 280 people, and the girl is a boy 13 14, then the number of girls is Lu Qin 260.

540 27=20 20*13=260 20*14=280 So 280 boys and 260 girls.

Girls are boys' 13 14 It can be understood that the ratio of girls to boys is 13:14
