If there are 2 3 more boys than girls, then there are 20 fewer girls than boys, right?

That's not right. 40% is right. In other words, 2 3 is two-thirds of the meaning, and it can't be typed up and down.

I don't know what grade you're in.,So the steps are a little more detailed to understand.,It's going to be a lot of words.。。。

If the number of girls is set as unit 1, the number of boys is 2/3 more than the number of girls", that is, the boys add two-thirds of the number of girls to the girls, then the boys are 1+2 3 (i.e., one and two-thirds).

The number of female students is a few per cent lower than that of male students"That is"The proportion of girls who are less than boys in the number of boys"The formula can be set as [(male-female) male 100%] ("Male-female"represents the number of girls who are fewer than boys; The proportion is the percentage it makes up for the number of boys).

Male-female) Male 100%.

1 2 3-1) 1 2 3 100%.

2 3 3 5 100% (divided by a number equals the reciprocal of multiplying it) If you can't understand it, you can use the special value method.

Assuming that the number of girls is 60, the number of boys is 60 + 60 2 3 = 100.

Ratio: (100-60) 100 100%.

Female = Male (1 and 2 3).

Female = Male 5 3

Male = Female 3 5

Male-Female = Male-Male 3 5 = Male 2 5 = Male 40%.

So the title is incorrect.

The number of girls is the unit "1", and the number of boys is 1+2 3, that is, 5 3, the formula: (5 3-1) 5 3 = 2 5 = 40%, the question is incorrect.

No, if there are x boys and y girls x-y=2 3y, then x=5 , 2 3y x=2 5=40%.

Elementary school application questions are obviously not right, and the following are still counted? Is it taught by an elementary school math English teacher?

If there are one-third more boys than girls, then a few fractions less girls than boys.

Hello, the number of boys is 1/3 more than the number of girls, then the number of girls is 4 times less than the number of boys. Because the first sentence is to use the number of girls to make Duan Xun's unit one, and the problem is to do unit 1 by the number of boys.

The boys' team has more than the girls and is 1 3

Boys are 4 3 of girls

Girls are 3 to 4 boys

Girls are 1 4 fewer than boys

Let the boy x the girl be yTwo-thirds more men than women. Then filial piety, (x-y) y=2 3, that is, x y-1=2 3, then x cheating, y=5 3

Let's say there are 3 women. There are 5 males, (because of this simplicity) that is, women are less clever than males (5-3) 5=2 5, not talented.

Just remember that it's just a play on words. That's it!

Here's how, please refer to:

The number of female students is lower than that of male students.

There are more boys than girls.

According to the title, the number of girls is less than that of boys (35-30) 35 is approximately equal to, and the number of boys is more than that of girls (35-30) 30 is approximately equal to .

Girls are 10 percent less than boys, and boys are more than girls.

Solution: There are 1 3 more boys than girls

Boys are 4 3 of girls

Girls are 3 to 4 boys

Girls are 1 4 fewer than boys

The number of boys is 2 3 of girls, which can be seen as 2 boys and 3 girls.

The number of boys is about less than that of girls, and the column formula: (3 2) 3 is approximately equal to.

There are 50 more girls than boys, and the column formula: (3 2) 2 50

A: There are 40 percent fewer boys than 40 percent more girls than boys.
