In a math test, 35 students in Class 5 (2) achieved excellent results. In the medium term, the number of boys is exactly 1.5 times that of girls. How many boys and girls have excellent grades? (Equation)
Solution: If there are X students among girls, there are 1.5X students among boys.
The equation derived from the meaning of the question is: 1.5X number of outstanding boys +X number of outstanding girls = total number of outstanding students in 35 classes.
The solution is X= 14.
1.5X = 1.5× 14 = 2 1
A: Girls 14, boys 2 1.
