Boys are 1 / 4 less than girls, and the number of boys is equivalent to a few percent of the number of girls

Boys are 1 / 4 less than girls, and the number of boys is equivalent to a few percent of the number of girls

The number of male students is 1 / 4 less than that of female students, that is to say, the number of female students is regarded as 1, and the number of male students is 1-1 / 4 = 3 / 4, that is, the number of male students is equal to three fourths of the number of female students
Given AB & # 178; = - 6, find the value of the algebraic formula - AB (A & # 178; B ^ 5-ab & # 179; - b)
-ab(a²b^5-ab³-b)
=-ab²(a²b^4-ab²-1）
=6（36+6-1）
=6×41
=246
There are 45 students in class one of grade five, including 28 boys. What is the percentage of boys in the class? What is the percentage of girls in the class?
schoolboy:
28 △ 45 = 28 / 45
girl student:
（45-28）÷45
=17÷45
=17 out of 45

How much does √ 3.6 & # 178; + 2.4 & # 178; equal? Solve
√3.6²=3.6,
2.4 & # 178; = 5.76, the total is 9.36
The number of male students in a class is 5 / 6 of that of female students. What is the number of male students in the class?
You see, we can draw a line segment, one is one centimeter, and boys are 5 / 6 of girls. If girls are regarded as one, boys are 5 / 6 of girls. If girls are 6, boys are 5 (draw line segment, girls are 6cm, boys are 5cm), then the number of students in the class = boys + girls = 5 + 6 = 11
(- 3 & # 178;) - # 178; how much is it=
(-3²)²=(-9)²=9²=81
The ratio of girls to boys in a class is 5:6;
How many are the number of girls, how many are boys more than girls, and how many are girls less than boys?
The ratio of girls to boys in a class is 5:6. Boys account for a fraction of the total number of students in the class, 6 ^ (5 + 6) = 6 / 11 (six out of eleven) girls account for a fraction of the total number of students in the class, 5 ^ (5 + 6) = 5 / 11 (five out of eleven) girls account for a fraction of the total number of students, 5 ^ (6 = 5 / 6 (five out of six) boys are more than girls
Men account for 6 / 11 of the class, women account for 5 / 11 of the class, women are 5 / 6 of men, men are 1 / 5 more than women, women are 1 / 6 less than men.
Male students account for 6 out of 11, female students account for 5 out of 11, female students account for 5 out of 6 of male students, male students account for 1 out of 11, and female students account for 1 out of 11
Think about the proportion of boys in the whole class. The total number of girls and boys in the class is 5 + 6, that is 11. Boys account for 5 / 11, that is five out of eleven. Then girls are 6 / 11, that is, girls account for five out of six in boys, that is, boys account for more than girls, that is, boys account for more than girls, that is, girls account for more than girls（ 6-5 / 5, that is, one in five, and the percentage of girls who are less than boys is (6-5 / 6), that is, one in six.
Thank you for... Unfolding

What is the sum of (179; √ 3) & (178
The answer is two-thirds power of 3, which is 2.080838231. Remember the operation rules of exponential power of rational number. The base of index addition and subtraction is the same, and it is multiplied and divided by the base power. The base of index multiplication is the same, and the power of power should be clear
