Two fifths
1 / 4 x + square of X + cube of X
1/4 x＋x²＋x³＝1/4 x（1＋4x＋4x²）
＝1/4 x（1＋2x）²
There are 24 boys and 18 girls in class 51. The number of girls is a fraction of that of boys, and the number of boys accounts for a fraction of that of the whole class
Analysis: by dividing the number of girls by the number of boys, the number of girls is a fraction of the number of boys;
Find out the number of the class, and then divide the number of boys by the number of the class
18÷24=3/4
;
24÷（24+18）,
=24÷42,
= 4/7
;
A: the number of girls is equivalent to three-quarters of the number of boys
Boys account for 4 / 7 of the class
This problem belongs to a basic type in the application of fractional division: if two numbers are known, how many fractions of one is the other
18 / 24 = 3 / 4 girls are three-quarters of boys
24 / 42 = 4 / 7 boys are four seventh of the class
18÷24=¾
24 ÷ (18 + 24) = 4 / 7
18÷24=3/4
24/（18+24）=4/7
A: the number of female students is 3 / 4 of that of male students, and the number of male students accounts for 4 / 7 of the class

There are 24 boys and 26 girls. How many times are boys and girls
Boys are 12 out of 13 girls and girls are 13 times of 12 boys
How many minutes is 1 hour + 30 minutes + 15 minutes + 20 minutes + 1 hour + 20 minutes
=60+30+15+20+60+20
=205 minutes

205 minutes, asking: how many hours
There are 25 boys and 23 girls in class 1 of grade 6. What percentage of boys are girls? What percentage of the class are boys?
23 / 25 = 92%; 25 / 25 (25 + 23) = 25 / 48, ≈ 52%
How many hours is 15 minutes
A quarter of an hour
Girls are 25% more than boys. What percentage of the class are girls?
Be sure to write the process
Let X be the number of men, because there are 25% more girls than boys, so the number of girls is 5 / 4 X
Then the total number of the class is x + 5 / 4 x = 9 / 4 X
The ratio of girls is 5 / 4 x △ 9 / 4 x = 5 / 9
How many hours is 2 hours 15 minutes 30 seconds
2 + 15 / 60 + 30 / 3600 = 2 + 1 / 4 + 1 / 120 = 271 / 120 hours
two point two five eight three
two point two five eight three three three three three
All in seconds
2 hours = 3600 * 2 = 7200 seconds
15 minutes = 60 * 15 = 900 seconds
Total 7200 + 900 + 30 = 8130 seconds
8130 / 3600 = 2.583333333 hours
2 hours 15 minutes 30 seconds=
(2 + 15 / 60 + 30 / 3600) hours=
2.2583 hours
