If one-half of the number a is equal to three-quarters of the number B, then what is the ratio of a to B
This question is too familiar. It's right to ask me. I'm Xiao Liu
A × 1 / 2 = B × 3 / 4
So a = 1 divided by 1 / 2, B = 1 divided by 3 / 4
A = 2, B = 4 / 3
A: B = 2: 4 / 3
A: B = 3; 2
A × 1 / 2 = B × 3 / 4
A: B = 3 / 4:1 / 2
Let a be x and B be y
Then two thirds of x equals three quarters of Y, and x equals three to eight
So a is three to eight
Let's take both sides as one, then a is two, B is four thirds, two and four thirds are reduced to the simplest integer, and the ratio level is 2 divided by Four Thirds equals three quarters, which is three to two
One half of the number a is equal to three fourths of the number B, so two sides multiply by four to get 2 a = 3 B, so a is better than B = 3:2

A × 1 / 2 = B × 3 / 4
So a = 1 divided by 1 / 2, B = 1 divided by 3 / 4

A: B = 3; 2
There are 96 people in the children's palace chorus, and the number of the dance team is 21 less than three times that of the chorus. How many people are there in the dance team?
96X3-21=267
If 4 / 3 of a is equal to 3 / 2 of B, what is the ratio of a to B?
Let a be x, B be y, then according to the question: X * 4 / 3 = y * 3 / 2 → x = 9 / 8y → X: y = 9:8
Students take part in extracurricular interest classes. The number of students who take part in the art group is twice that of the dance group. If 126 students take part in the interest group, how many people take part in the dance group?
126/（2+1）=42
Seven eighths of the number a is equal to four ninths of the number B. the two numbers a and B are in proportion. The ratio of the number a to the number B is ()
Seven eighths of the number a is equal to four ninths of the number B. the number a and the number B are in (positive) proportion. The ratio of the number a to the number B is (32:63)
There are two more girls than boys in a class. The ratio of boys to girls is 10:11. How many boys and girls are there in this class?
There are 20 male students and 22 female students. The number of female students is 2 × 11 = 22. The number of male students is 10 × 2 = 20. A: there are 20 male students and 22 female students
The average number of the three numbers is 120. The number a is twice that of the number B. the number C is 4 more than the number A. what are the three numbers a, B and C?
Let B be x, then a be 2x and C be 2x + 4. According to the meaning of the question, we can get the equation: x + 2x + 2x + 4 = 120 × 3 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 5x + 4 = 360 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 5x = 356 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 71.2
The ratio of boys to girls in class 6 (1) is 11 to 10. Girls are 2 less than boys. How many students are there in class 6 (1)?
2X (11-10) / (11-10)
=2x21/1
=42 (person)
The average number of the three numbers is 120. The number of a is twice that of B. the number of C is 5 more than that of A. what are the numbers of a, B and C?
Let B number be x, then a number be 2x and C number be 2x + 5. According to the meaning of the question, we can get the equation: x + 2x + 2x + 5 = 120 × 3 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 5x + 5 = 360 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 5x = 355 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 71, so a number
