Simple operation of 96 times 125 divided by 48

The denominator of two-thirds should be expanded six times. If the size of the fraction remains unchanged, the denominator should be added with ()
We should talk about the truth of the topic

10. The denominator 3 of thinking should be expanded by six times. If we want to keep the score unchanged, the numerator 2 should also be expanded by six times. After expansion, it is 12, increased by 10

The denominator of two-thirds is 36, and the fraction with the same size is 36

The denominator is 36, that is, multiply 3 by 12. In order to keep the size of the fraction unchanged, multiply 2 by 12 to get 24. The fraction is 24 out of 36

Divide a score, use 3 about 2 times, use 2 about once, and finally get two fifths. What is the original score?

Go back ~! The numerator and denominator are multiplied by 2 once and 3 twice at the same time
That is, (2 * 2 * 3 * 3) / (5 * 2 * 3 * 3) = 36 / 90

How much is (20 + two fifths) multiplied by 2?

The number of girls in the school sports team used to be two-thirds of the number of boys. Later, five girls took part. This is the ratio of the number of girls to the number of boys, which is 7:8. How many students are there in the school sports team? Three bucks

First of all, we know that the number of girls in the sports team is two-thirds of the number of boys. Then we can regard it as two for girls and three for boys. Later, there are seven for girls and eight for boys. So we use seven eighths minus two-thirds to get five twenty-four. That is to say, the corresponding amount of five twenty-four is five people. So we divide five by five twenty-four to get 24, So there are 24 people in this team! Give me some points

The number of football used to be two fifths of Volleyball in school physical education room, but one volleyball was eliminated later. Now the number of football is three seventh of volleyball

The number of science and technology interest groups is three fifths of the number of sports interest groups, and the number of literature and art is two fifths of the number of sports, so the number of literature and art is the number of science and technology
The answer is complete
What fraction?

The number of sports interest groups is X
The number of science and technology interest groups is 3 / 5x;
The number of interest groups is 2 / 5x;
The number of literati in namo is the number of scientists and technicians: 2 / 5 divided by 3 / 5 = 2 / 3
The answer is two-thirds

The school carried out extracurricular interest group activities. The ratio of the number of literature and art group and sports group was 4:3. Later, the number of literature and art group increased by 4. At this time, the number of sports group was 23 times that of literature and art group?

4 △ 32-43, = 4 △ 16, = 24 (people); 24 × 32 = 36 (people); answer: there are 36 people in the literature and art group now

I hope that the number of students who have reached the standard in physical education is 3 / 5 of those who have not reached the standard. Later, there are 60 students who have reached the standard
The number of students is 9 out of 11 who fail to meet the standard. How many students do you want to have in primary school

The total number has not changed
It turns out that the number of people who reach the standard: the number of people who fail to reach the standard = 3:5, and the number of people who reach the standard accounts for 3 / (3 + 5) = 3 / 8 of the total number
Later, the number of qualified people: the number of unqualified people = 9:11, the number of qualified people accounted for 9 / (9 + 11) = 9 / 20 of the total number
Total number of students in hope primary school = 60 (9 / 20-3 / 8) = 800
